Introduction
The Sixteen Bodhisattva Precepts occupy a unique place within Soto Zen Buddhism. They are at once vows, ethical principles, contemplative teachings, and expressions of awakening itself.
For centuries they have been transmitted to monks, priests, and lay practitioners through the ceremony of Jukai, the reception of the precepts, and have served as a guide for living the Buddha Way.
The commentaries that follow are not intended as authoritative interpretations. Rather, they are personal reflections developed through years of Zen practice, study, contemplation, and participation in the Soto Zen tradition. They draw upon Buddhist scriptures, Zen literature, monastic teachings, and lived experience, while remaining grounded in the spirit of inquiry that has always characterized the Buddhist path.
The precepts may be understood in many ways. Some practitioners view them primarily as ethical guidelines. Others see them as descriptions of enlightened conduct. Still others regard them as mirrors that reveal the condition of the mind in each moment. In Soto Zen, these perspectives need not be mutually exclusive. The precepts can function simultaneously as aspirations, practices, and realizations.
What has always impressed me most about the Bodhisattva Precepts is their practicality. They are not concerned with abstract theology or metaphysical speculation. They address the realities of everyday life: how we treat other living beings, how we speak, how we conduct relationships, how we respond to anger, how we participate in community, and how we cultivate wisdom and compassion.
The precepts are not commandments handed down by a distant authority. They are invitations to examine one’s life honestly. They encourage mindfulness, integrity, generosity, humility, and concern for the welfare of others. At their best, they transform Buddhist practice from something confined to the meditation cushion into something embodied in every aspect of daily life.
Like all Buddhist teachings, the precepts reveal new meanings as one matures in practice. A vow that appears simple at first may reveal unexpected depth after years of contemplation. A precept that once seemed restrictive may later be recognized as an expression of freedom. What follows, therefore, should be understood not as final conclusions, but as reflections along an ongoing path of study and practice.
The Bodhisattva Precepts are ultimately about awakening in relationship—to oneself, to others, and to the world. They point toward a life grounded in wisdom and compassion, lived not for personal gain alone, but for the benefit of all beings.
Historical Foundations
The Vinaya: The Roots of Buddhist Ethics
The ethical foundations of Buddhism reach back to the lifetime of Shakyamuni Buddha in northern India during the fifth century BCE. As the Buddha’s community of monks and nuns grew, practical guidelines became necessary to support harmony, discipline, and spiritual practice. Over time, these guidelines were collected into what became known as the Vinaya, the monastic code of Buddhist conduct.
The Vinaya forms the first division of the Tripitaka, the traditional Buddhist Canon. Alongside the Sutras, which record the Buddha’s teachings, and the Abhidharma, which systematizes Buddhist philosophy, the Vinaya preserves the ethical framework upon which Buddhist practice is built.
The rules of the Vinaya were not originally presented as abstract moral commandments. Most arose in response to specific situations encountered within the early Buddhist community. In this way, the Vinaya developed organically, addressing practical concerns while expressing deeper principles of compassion, wisdom, restraint, honesty, and communal harmony.
The Buddha summarized his teaching through the Noble Eightfold Path, traditionally grouped into three categories: ethical conduct (sila), wisdom (prajna), and meditation (samadhi). The Vinaya is the fullest expression of sila. It translates Buddhist principles into daily life, shaping behavior in ways intended to reduce suffering and cultivate awakening.
Yet the Buddhist understanding of ethics differs from many legalistic systems. The Vinaya was never intended as a rigid collection of rules divorced from circumstance or wisdom. Buddhist ethics begins with intention. Actions are evaluated not merely by outward conformity but by the mental states that motivate them. For this reason, compassion, mindfulness, and discernment remain essential to ethical practice.
Throughout Buddhist history, communities have adapted the practical application of monastic regulations to new cultures and circumstances while preserving the underlying principles that support awakening. This balance between continuity and adaptation became one of the defining characteristics of Buddhist ethical traditions.
The Evolution of the Bodhisattva Precepts
Throughout Buddhist history, communities have adapted the practical application of monastic regulations to new cultures and circumstances while preserving the underlying principles that support awakening. This balance between continuity and adaptation became one of the defining characteristics of Buddhist ethical traditions.
The Bodhisattva Precepts of Mahayana Buddhism are derived from the Pratimokṣa, the body of rules contained within the Vinaya. The Vinaya itself is among the earliest Buddhist literature, some portions of which may date to the Buddha’s own lifetime. As the practical embodiment of Buddhist ethics, it represents the application of the Noble Eightfold Path to everyday conduct and communal life.
The Noble Eightfold Path is traditionally divided into Sila (Ethics), Prajna (Wisdom), and Dhyana or Samadhi (Meditation). The Vinaya is the fullest expression of Sila. It provides the ethical structure through which wisdom and meditation may flourish. The Bodhisattva Precepts, as they later developed within Mahayana Buddhism, may be understood as a concise and accessible expression of this ethical tradition.
The Precepts do not form a rigid code of laws carved in stone. Rather, they are, in essence, a description of how the bodhisattva manifests in the world. Their purpose is not merely to regulate behavior, but to cultivate the wisdom and compassion that characterize awakened life.
The core principles of the Vinaya have remained remarkably stable throughout Buddhist history. The Buddha’s ethical teachings are preserved not only in the Vinaya itself, but also throughout the Sutras, the second division of the Tripitaka.
There has long been debate concerning the “minor rules” that the Buddha reportedly permitted future generations to modify. This discussion dates back to the First Buddhist Council, traditionally held shortly after the Buddha’s death. According to Buddhist tradition, Mahakasyapa, the Buddha’s successor, argued that no rules should be discarded.
By the time of the Second Buddhist Council, disagreements regarding monastic discipline contributed to the earliest divisions within the Buddhist community. One group, represented today by the Theravada (or Nikaya) traditions, maintained that the Vinaya should be preserved without alteration.
Other emerging traditions were generally more open to adaptation. Over time, these differences became associated with broader developments that eventually contributed to the rise of Mahayana Buddhism. The former traditions preserved their scriptures primarily in Pali and became associated with the Buddhist cultures of South and Southeast Asia, while the latter increasingly employed Sanskrit and became influential throughout northern Asia.
Several versions of the Vinaya subsequently developed, including the Theravada Vinaya of South and Southeast Asia, the Mūlasarvāstivāda Vinaya preserved in Tibet, and the Dharmaguptaka Vinaya that became standard throughout East Asia and remains the ordination lineage of Chan and Zen Buddhism.
Considering the Mahayana principle of expedient means—the teaching that the Dharma may be presented in different ways according to the needs of different people—such diversity among Buddhist lineages is perhaps inevitable. Rather than a weakness, it may be viewed as one of the strengths of the Buddhist tradition: a capacity to preserve its essential principles while adapting to new cultures, languages, and historical circumstances.
The history of the Vinaya therefore illustrates a central feature of Buddhism itself: fidelity to enduring principles combined with a willingness to adapt skillfully to changing conditions. From this foundation, the Bodhisattva Precepts would emerge as one of the most influential ethical systems in the Mahayana tradition.
Buddhist Monastic Rules
The Soto Zen tradition inherited centuries of Buddhist ethical development from India, China, and Japan.
When Buddhism entered China, the Indian Vinaya proved difficult to apply in its original form within Chinese society. In response, new monastic regulations known as “Pure Standards” (Qinggui) were developed, drawing upon both Buddhist principles and traditional Chinese social and governmental structures. These texts adapted Buddhist monastic life to Chinese culture while preserving the essential principles of the Dharma.
Among the most influential were the eighth-century Pure Rules of Baizhang and Changlu Zongze’s Chanyuan Qinggui (Pure Rules for Chan Monasteries), compiled in 1103. These works helped shape Chan Buddhist communities for centuries. Dogen would later build upon this tradition in Japan through his Eihei Shingi, or Pure Standards for the Zen Community.
Soto Zen and the Sixteen Bodhisattva Precepts
The anonymous fifth-century Indian Brahmajala Sutra, translated from Sanskrit into Chinese by Kumārajīva around 406 CE, lists ten major Bodhisattva vows and forty-eight minor Bodhisattva vows. Dogen Zenji adopted these ten major vows, known in Japanese as the Jūjū Kinkai (“Ten Grave Precepts”), as the foundation of the Soto Zen Bodhisattva Precepts for both monks and lay practitioners.
To these, Dogen added the Three Refuges found throughout the Vinaya and the Sutras, as well as the Three Pure Precepts derived from the famous verse of the Dhammapada (verse 183), which had long been incorporated into Chan ordination traditions. The result was the system known today as the Sixteen Bodhisattva Precepts, still received by both lay and ordained practitioners throughout the Soto Zen world.
When Zen was transmitted to Japan, Eihei Dogen Zenji drew deeply from both the Indian Vinaya tradition and the Chinese Chan monastic heritage. Dogen regarded the precepts as inseparable from Zen practice itself. For him, ethics, meditation, and awakening were not separate disciplines but different expressions of a single reality.
This perspective found formal expression in his Kyojukaimon, the text used in Soto Zen ordinations. There, Dogen combined the Three Refuges, the Three Pure Precepts, and the Ten Grave Precepts into a unified ethical framework.
Together these became known as the Sixteen Bodhisattva Precepts.
The Three Refuges establish one’s relationship with the Three Treasures—Buddha, Dharma, and Sangha. The Three Pure Precepts summarize the cultivation of ethical living and compassionate action. The Ten Grave Precepts address the major forms of conduct that either support or obstruct awakening.
Unlike legal codes, these precepts are understood in Soto Zen as descriptions of enlightened life rather than external commandments. They point toward a way of being characterized by wisdom, compassion, integrity, generosity, and respect for all life.
Dogen taught that receiving the precepts is not merely a ceremonial event. It is an affirmation of one’s participation in the Buddha Way itself. Through the ceremony of Jukai, practitioners formally receive the precepts and undertake the lifelong work of embodying them in thought, speech, and action.
The Shushogi, commonly translated as The Meaning of Practice and Enlightenment, was compiled as a concise presentation of Soto Zen teachings drawn largely from Dogen’s Shobogenzo. Unlike many modern introductions to Zen, the Shushogi is not primarily concerned with meditation technique. Rather, it emphasizes themes such as repentance, faith, karma, causation, and the transmission of the Buddha-Dharma.
The text teaches that shikantaza—”just sitting”—is itself practice-realization, but it also presents the Bodhisattva Precepts as an expression of the realization that “Mind itself is Buddha.” It further affirms the traditional Zen understanding that the Buddha-Dharma is transmitted mind-to-mind from Shakyamuni Buddha to Mahakasyapa and through the generations of ancestors and teachers.
In the late nineteenth century, the Soto Zen school established a committee known as the Soto Fushukai, or Soto Assembly for Upholding the Tradition, under the leadership of the layman Ouchi Seiran Koji (1845–1918). Ouchi edited Dogen’s Shushogi, which the committee published as the Tojo Zaike Shushogi (The Meaning of Practice and Verification for Lay People in the Soto Tradition).
Soon afterward, the two head abbots of the Soto Zen school—Azegami Baisen Zenji of Sojiji and Takiya Takushu Zenji of Eiheiji—issued a revised edition in 1890. Published as the Soto Kyokai Shushogi (The Meaning of Practice and Verification of the Soto Teaching Assemblies), this version became the standard presentation of Soto Zen teaching and remains highly influential within the Soto school to the present day.
Today, the Sixteen Bodhisattva Precepts continue to serve as the ethical foundation of Soto Zen practice throughout the world. They connect modern practitioners to a living tradition that extends from the Buddha and the early Sangha, through the great masters of India, China, and Japan, and into the present day.
They remain not only a guide for conduct but a profound expression of the awakened life itself.
The author is grateful that he does not have to take the Shramanera Ten Precepts directly from the Pali Canon, because several of the later precepts seem to be products of a particular monastic culture and historical period rather than universally applicable principles for contemporary practitioners.
Shramanera Ten Precepts (Shamijūkai 沙彌十戒)
(Luminous Owl translation)
- The precept not to kill living beings (fusesshōkai 不殺生戒).
- The precept not to steal (fuchūtōkai 不偷盜戒).
- The precept not to engage in sex (fuinyokukai 不婬欲戒).
- The precept not to engage in false speech (fumōgokai 不妄語戒).
- The precept not to drink alcohol (fuinshukai 不飲酒戒).
- The precept not to wear flower garlands or adornments, nor to perfume the body (不著華鬘瓔珞香油塗身戒).
- The precept not to sing, dance, play music, or attend such entertainments (不歌舞作唱故往觀聽戒).
- The precept not to sit or lie upon a high, wide, or luxurious bed (不坐臥高廣大床戒).
- The precept not to eat at improper times, traditionally between midday and dawn (不非時食戒).
- The precept not to receive or possess gold, silver, money, or precious objects (不捉金銀錢寶戒).
The Bodhisattva Precepts used in Soto Zen derive more directly from the fifth-century Brahmajala Sutra (Brahma’s Net Sutra), the earliest known source for what would later become the Ten Grave Precepts (SZBA, The Evolution of the Precepts, 2008, p. 74):
- On Killing
- On Stealing
- On Sexual Misconduct
- On Lying and False Speech
- On Selling Alcoholic Beverages
- On Broadcasting the Faults of the Assembly
- On Praising Oneself and Disparaging Others
- On Stinginess and Abuse
- On Anger and Resentment
- On Slandering the Triple Jewel
The historical development of the Bodhidharma Precepts is somewhat complex. As Robert Baker Dairyu Chotan Aitken Rōshi notes in “The Evolution of the Precepts”: Study Material for the 2008 National Conference of the Soto Zen Buddhist Association:
“The history of the Bodhidharma precepts is complicated, and there are many different versions. They are not composed by Bodhidharma but rather arose in Japan as part of Tendai efforts to establish a new Vinaya. The earliest extant version of the Bodhidharma One-Mind Precepts dates from the mid-fifteenth century.”
Despite questions of authorship, the Bodhidharma Precepts became highly influential in Zen. Several modern Zen teachers have emphasized the same central theme:
“The precepts are not rules to bind us. They are the living skin of the Buddha. To touch them is to touch the Buddha Mind itself; to practice them is to let the Buddha breathe through your own life.”
— Dainin Katagiri Roshi
“To receive is to transmit. To transmit is to be awakened. Thus to be awakened in Buddha Mind is called true receiving of the precepts.”
— Kobun Chino Otogawa Roshi
“To receive is to transmit; to transmit is to awaken; and to awaken the Buddha Mind is called true Jukai. Each precept is a vignette of the One Mind that is always with us.”
— Jakusho Kwong Roshi
Dogen’s Kyojukaimon, the eighty-third chapter of the Shobogenzo, remains the standard Soto Zen presentation of the Bodhisattva Precepts. Dogen taught that receiving the precepts is among the most important acts of Buddhist ordination. The Kyojukaimon describes the ordination ceremony that confers the “Transmission of the Treasure House of the Eye of the True Teaching.” It begins with the Three Refuges and proceeds through the Three Pure Precepts and the Ten Grave Precepts.
One aspect of the Zen tradition that fascinates the author is the esteem in which the precepts are held. In the graded kōan curriculum of the Linji (Rinzai) school, the highest kōans concern the precepts themselves, followed by the Five Ranks of Dongshan.
To this day, Chan and Zen practitioners revere Dongshan Liangjie (807–869), the founder of the Caodong lineage, as one of the most influential figures in their tradition. His poem The Five Ranks, inspired by the Yijing (I Ching) and perhaps also by the Sandokai, became foundational to Caodong philosophy. His Jewel Mirror Samadhi (Baojing Sanmei, Japanese Hōkyō Zammai), another poetic expression of the same vision, continues to be chanted in Soto Zen temples throughout the world.
It is therefore not surprising that the precepts occupy such a central place within Zen. They are not merely rules of conduct. They are regarded as expressions of awakening itself—manifestations of the Buddha Mind in everyday life.
Introducing the Sixteen Bodhisattva Precepts
The Sixteen Bodhisattva Precepts are traditionally received during the Soto Zen ceremony of Jukai, the reception of the precepts. They represent the ethical foundation of Zen practice and serve as a guide for living the Buddha Way in daily life.
The precepts are divided into three groups: the Three Refuges, the Three Pure Precepts, and the Ten Grave Precepts. Together they summarize the essential principles of Buddhist faith, practice, and ethical conduct.
The Three Refuges establish one’s commitment to the Three Treasures of Buddhism: Buddha, Dharma, and Sangha. The Three Pure Precepts express the universal aspiration to refrain from harm, cultivate goodness, and benefit all beings. The Ten Grave Precepts provide practical guidance for embodying wisdom and compassion in everyday life.
In Soto Zen, these precepts are not regarded as commandments imposed from outside oneself. Rather, they are understood as expressions of Buddha-nature itself. They reveal how awakened awareness naturally manifests through conduct, speech, relationships, and community life.
The following translation reflects the form commonly used within contemporary Soto Zen practice.

Commentary on the Three Refuges
The Three Refuges stand at the beginning of Buddhist practice.
For more than two thousand years, they have served as the formal entrance into the Buddhist path. Whether one is a monk, priest, or lay practitioner, taking refuge in Buddha, Dharma, and Sangha signifies a commitment to awakening, wisdom, and compassionate community.
The refuges are not merely statements of belief. They are expressions of direction. To take refuge is to orient one’s life toward what is true, beneficial, and liberating. In this sense, refuge does not imply dependence or submission. Rather, it signifies confidence in a path that has guided generations of practitioners through the challenges of human life.
Within Soto Zen, the Three Refuges are not regarded as separate from enlightenment itself. Dogen taught that practice and realization are one. Thus, taking refuge is already an expression of awakening. It is the activity of Buddha-nature recognizing and affirming itself.
Taking Refuge in the Buddha
Buddha means “Enlightened One” or “Awakened One.” Enlightenment is both practice and realization. It encompasses Sila, Prajna, and Samadhi—ethics, wisdom, and meditative insight. Ethics are founded upon compassion; wisdom is cultivated through study, meditation, and experience; and insight arises through zazen and the direct realization of one’s true nature.
The historical Buddha, Siddhartha Gautama, taught this path as the Dharma. His teachings were transmitted orally for generations before being recorded in the Vinaya, the monastic discipline, and the Sutras, the sermons and stories that form the heart of the Buddhist tradition. Over time these collections, together with the Abhidharma, or scholastic commentaries, came to be known as the Tripitaka, the Three Baskets of Buddhist scripture.
The Buddha of history is inseparable from the Buddha of practice. To take refuge in Buddha is not merely to honor a teacher who lived twenty-five centuries ago. It is also to place confidence in the possibility of awakening itself.
In Zen, Buddha is both a person and a principle. The historical Buddha demonstrated that liberation from suffering is possible. At the same time, Buddha-nature is understood to be inherent within all beings. Taking refuge in Buddha therefore means trusting that wisdom and compassion can be cultivated within one’s own life.
For this reason, refuge is not blind belief. It is a commitment to practice, inquiry, and realization. One takes refuge in the example of the Buddha, in the possibility of awakening, and in the aspiration to embody that awakening for the benefit of all beings.
Taking Refuge in the Dharma
The Dharma begins with the Four Noble Truths, the Precepts, and the Vinaya, and includes the Tripitaka and all Buddhist teachings throughout space and time. A bodhisattva follows the Noble Eightfold Path and takes the Bodhisattva Vows. Lay practitioners seek to live in accordance with these teachings, while monastics undertake a formal discipline such as the ancient Indian Patimokkha Rules, the Chinese Dharmaguptaka Vinaya, or Dogen’s Eihei Shingi, the Pure Standards for the Zen Community.
The Buddha taught that expedient means should be used to guide diverse people according to their needs, capacities, and circumstances. Because people differ, teachings must sometimes be presented in different ways. Likewise, Buddhist institutions and practices must adapt to time and place while preserving the essential principles of the Dharma. This concept finds its most famous expression in the Lotus Sutra.
To take refuge in the Dharma is therefore not simply to accept a body of teachings. It is to commit oneself to a lifelong process of study, practice, inquiry, and realization. The Dharma is both the path and the truth toward which the path points. It is found in scripture, in meditation, in daily life, and in the wisdom gained through experience.
Taking Refuge in the Sangha
The Sangha is the community of Buddhists with whom one practices.
A healthy community benefits every member when each able member contributes to its well-being and strives to live harmoniously with others. In many ways, a community functions as a single body. Just as the health of the body depends upon the proper functioning of its various parts, the health of a sangha depends upon the care, effort, and goodwill of its members.
Family and community are among the most important dimensions of human life. The sangha becomes an extension of both. Its well-being is therefore in the interest of every person who calls it home. The sangha supports each member in practice, and each member bears some responsibility for supporting the sangha in return.
This mutual relationship is one of the treasures of Buddhism. No one practices entirely alone. We learn from teachers, friends, fellow practitioners, and even from those with whom we disagree. Together we create the conditions in which wisdom and compassion may flourish.
A community of bodhisattvas and buddhas is a powerful force for good in the world. Through cooperation, friendship, and shared practice, the Sangha becomes a living expression of the Buddha-Dharma.
Commentary on the Three Pure Precepts
The Three Pure Precepts summarize the ethical heart of the Bodhisattva Way. While the Three Refuges establish one’s relationship with the Buddha, the Dharma, and the Sangha, the Three Pure Precepts express how that refuge is embodied in daily life.
Derived from the well-known verse of the Dhammapada (183)—”To avoid all evil, to cultivate the good, and to purify one’s mind”—these precepts have long served as a concise summary of Buddhist ethics. In the Soto Zen tradition, they are expressed as vows to refrain from all evil, to make every effort to live in enlightenment, and to live for the benefit of all beings.
These are not merely moral obligations. They describe the natural activity of an awakened mind. Rather than imposing external rules, they encourage the cultivation of wisdom and compassion through mindful thought, speech, and action.
Together, the Three Pure Precepts form the bridge between inner realization and outward conduct. They remind us that awakening is not confined to meditation but is revealed in the ordinary choices we make each day.
To Refrain From All Evil
Evil may be understood as the opposite of the Good, the contradiction of ethics, wisdom, and compassion.
The Buddha taught that craving, attachment, and delusion are among the primary roots of suffering. When we act under their influence, we create harm for ourselves and others. The purpose of ethical practice is therefore to see through illusion with insight and to diminish the power of destructive desires through wisdom and self-awareness.
At its most practical level, this precept is a commitment to follow the Way. The rules and teachings exist not as arbitrary restrictions but as guides that help prevent harmful conduct. Evil, in this sense, is that which opposes awakening and contributes to suffering.
To refrain from evil is not merely to avoid wrongdoing. It is to cultivate awareness, discernment, and responsibility in every aspect of life.
To Make Every Effort to Live in Enlightenment
The Way of Enlightenment is the Buddhist Path.
It begins with cultivating the Good, examining one’s own life, and gradually realizing that the separate self we ordinarily cling to is not as solid or permanent as it appears. Buddhism teaches that all things are impermanent and interconnected. As insight deepens, attachment to a fixed and isolated self begins to loosen.
This realization forms the foundation of the bodhisattva’s life. Seeing less distinction between self and other, the practitioner naturally becomes concerned with the welfare of all beings. Ethics and compassion arise not from obligation alone, but from a deeper understanding of reality.
The word bodhisattva is often translated as “enlightening being.” A bodhisattva is one who seeks awakening while helping others move toward awakening as well. To live in enlightenment is therefore not merely to possess insight, but to embody that insight through wisdom, compassion, and action.
To Live for the Benefit of All Beings
While Buddhism teaches that the distinction between “self” and “other” is ultimately a matter of perception, the experience of living beings remains very real. People seek happiness, avoid suffering, and possess fundamental needs for survival, security, dignity, and meaning.
Human beings occupy a unique position in Buddhist thought. Though often caught in illusion and confusion, they also possess the capacity to realize their Buddha-nature. This possibility carries with it a profound responsibility.
The bodhisattva recognizes the interconnectedness of all life and seeks to act accordingly. Seeing the oneness and interpenetration of all beings, one naturally lives for their benefit. Compassion arises from insight. The more clearly one understands reality, the more naturally one responds with kindness, generosity, and concern for others.
Good intentions alone are not enough. Compassion is strengthened by wisdom, and wisdom is fulfilled through compassionate action. For this reason, the bodhisattva strives not merely to understand the Good, but to embody it.
To live for the benefit of all beings is the natural expression of an awakened heart.
Commentary on the Ten Grave Precepts
The Ten Grave Precepts are the practical expression of the Bodhisattva Way. Where the Three Refuges establish one’s spiritual foundation and the Three Pure Precepts summarize the ethical life, the Ten Grave Precepts apply those principles to the realities of everyday human conduct.
These precepts address how we relate to life, property, sexuality, speech, community, generosity, anger, and the Three Treasures. Although traditionally expressed as prohibitions, each also points toward a corresponding virtue. Not killing affirms reverence for life. Not stealing cultivates honesty and generosity. Not harboring ill will nurtures forgiveness and compassion. In this way, the precepts are not simply restraints upon behavior but guides to the positive qualities of an awakened life.
In Soto Zen, the Ten Grave Precepts are understood not as external commandments but as expressions of Buddha-nature itself. They invite continual reflection rather than rigid perfection, encouraging practitioners to cultivate wisdom and compassion in every aspect of daily life. Through their sincere practice, the ordinary activities of human life become opportunities to embody the Buddha Way.
Not to Kill
This vow must be interpreted with a practical mind. Traditionally, it refers primarily to sentient beings rather than plants. Some Buddhist monks take great care in the garden never to injure an earthworm. That is admirable. However, human beings host trillions of microorganisms and countless microscopic organisms upon and within their bodies. It is impossible to live without inadvertently causing the death of some forms of life.
We kill when we destroy harmful bacteria that threaten our health. We may kill while gardening, farming, building, cleaning, or simply going about our daily lives. Farmers may destroy insects and other pests in order to protect their crops. Even the most conscientious practitioner cannot entirely avoid causing harm.
For this reason, I understand the precept not as an impossible demand for absolute non-killing, but as a commitment to minimize harm and cultivate compassion. Personally, I have stopped killing ants and flies whenever possible, but if a mosquito is keeping me awake throughout the night, I will likely swat it, though I know some monastics would regard that as a lapse in practice.
The precept also has broader implications. It encourages nonviolence, discourages cruelty, and invites careful reflection upon occupations or activities that require directly harming others. Most plainly, it prohibits murder and the intentional taking of human life.
Questions concerning war, self-defense, capital punishment, euthanasia, and abortion remain subjects of debate among Buddhists, as they are among people generally. Individuals often arrive at different conclusions based upon their understanding of compassion, ethics, and the available evidence. Whatever one’s position, the spirit of the precept remains the same: reverence for life and a sincere effort to reduce suffering.
Ultimately, this vow expresses perhaps the most fundamental form of compassion. To value life, to protect life where possible, and to avoid unnecessary harm is a profoundly life-affirming attitude. The bodhisattva seeks not merely to refrain from killing, but to become a protector and supporter of life in all its forms.
Not to Take What Is Not Given
This vow refers to refraining from theft. Theft can take many forms, ranging from simple thievery to dishonest business practices, fraud, exploitation, and the misuse of trust.
The Buddhist monk is traditionally called a bhikṣu, literally a “beggar” or one who lives on alms. For a monk who depends entirely upon alms, this precept may be interpreted quite literally. For most modern practitioners, however, especially those living outside a monastery, earning a livelihood is both necessary and appropriate.
In contemporary life, the deeper meaning of the precept concerns honesty and integrity. Income may not be given freely, but it may be earned ethically. The bodhisattva therefore strives to earn a living honestly, to respect the property and rights of others, and to avoid benefiting from deception or exploitation.
At a broader level, this precept invites gratitude. Much of what sustains our lives comes through the efforts of others. Recognizing this interdependence naturally encourages respect, fairness, and generosity.
To refrain from taking what is not given is not merely to avoid stealing. It is to cultivate trustworthiness and honorable conduct in all aspects of life.
Not to Misuse Sexuality
In the Ten Stages chapter of the Avatamsaka Sutra, there appears a list of ten ethical principles known as the “Ten Good Ways of Action,” eight of which correspond closely to the Bodhisattva Precepts. There, sexual misconduct is defined quite simply:
“The enlightening beings also abandon sexual misconduct. They are satisfied with their own spouses and do not desire the spouses of others. They do not give rise to desire for others’ spouses, much less have sexual intercourse with them.”
In the Brahmajala Sutra, the interpretation of this precept was expanded to encompass a broader range of sexual misconduct. The emphasis remained on avoiding actions that cause harm, exploitation, betrayal, or suffering. This also accords with the teachings of the Tripitaka, where monks and nuns are generally expected to maintain celibacy.
Human sexuality manifests itself in many forms. Because individuals experience and express sexuality differently, it is difficult to create a single, universal description of proper and improper sexuality that accounts for every circumstance. What can be said with confidence is that sexuality, like all powerful aspects of human life, should be approached with mindfulness, responsibility, and moderation.
Ethical sexuality can only exist between mature, uncoerced, consenting partners of sound mind. Relationships involving significant imbalances of power deserve particular caution. Sexual relationships between a teacher and student, clergy and congregant, therapist and client, employer and employee, or similar authority figures and those under their care are ethically problematic because genuine consent may be compromised by the imbalance of power.
While abstinence certainly avoids sexual misconduct, healthy sexuality should not necessarily be regarded as inferior to celibacy. For many people, sexuality is a natural and normal part of life. The essential question is not whether one is sexually active, but whether one’s conduct is guided by honesty, respect, compassion, responsibility, and concern for the well-being of others.
The bodhisattva seeks relationships that cultivate trust, dignity, and mutual flourishing rather than attachment, exploitation, or harm.
To Refrain From False Speech
To maintain integrity, one’s thoughts, words, and actions should be in alignment. Integrity is essential to one’s overall well-being and forms the foundation of trust, character, and wisdom. False speech implies dishonesty, and dishonesty inevitably damages integrity.
When truthfulness becomes a priority, learning becomes a lifelong pursuit. One approaches the world with curiosity, skepticism, critical thinking, and compassion. Rather than clinging to comforting illusions, one seeks to understand reality as it is. This commitment to truth supports both personal growth and the cultivation of wisdom.
The bodhisattva therefore strives to speak honestly and responsibly. Truthful speech strengthens relationships, promotes understanding, and helps create harmony within the community. Through integrity, one can live a wholesome, meaningful, and joyful life.
To Refrain From Intoxicants
An important aspect of meditation is the clarity and insight it affords. Intoxication tends to produce the opposite effect, clouding perception, weakening judgment, and confusing the mind. For this reason, intoxicants have traditionally been discouraged in Buddhism, especially in relation to meditation practice.
Many intoxicants also carry the risk of dependency. Addiction often brings unnecessary suffering in the form of social difficulties, financial hardship, health problems, emotional distress, and damaged relationships. It is generally wiser to avoid such pitfalls before they become deeply rooted habits.
At the same time, Buddhism emphasizes the Middle Way. The spirit of this precept is not merely prohibition but the cultivation of awareness and self-mastery. If one chooses to partake of an intoxicant, excess and loss of self-control should be avoided.
The bodhisattva seeks to maintain clarity, dignity, and composure. By doing so, one becomes a positive example for others and preserves the mindfulness necessary for wisdom and compassion to flourish.
Not to Slander
Slander is the act of speaking falsely in order to damage another person’s reputation.
First, slander is a form of lying and therefore falls under the broader category of false speech. Second, slander is intended to injure another person, revealing a lack of compassion. Third, it is often socially destructive and, in some cases, may even carry legal consequences. Such behavior demonstrates poor judgment and a lack of wisdom.
The bodhisattva seeks to speak truthfully and compassionately. This does not mean avoiding honest criticism when criticism is warranted. Rather, it means speaking in ways that are fair, responsible, and intended to clarify rather than to harm.
An action that violates both compassion and wisdom cannot easily be reconciled with the Bodhisattva Way.
Not to Praise Self at the Expense of Others
I especially like this precept.
It is natural to take pride in one’s accomplishments, virtues, and achievements. It is equally natural to seek recognition and status. Yet human beings often attempt to elevate themselves by diminishing others. Whether through boasting, manipulation, ridicule, or subtle forms of social competition, we sometimes seek advantage at another person’s expense.
The bodhisattva vows to work for the benefit of sentient beings. Acting primarily for one’s own gain while undermining others runs contrary to that aspiration. Genuine confidence does not require belittling others, nor does true accomplishment require comparison.
Humility does not mean denying one’s strengths. Rather, it means recognizing them without needing to use them as tools of self-promotion or domination.
I would add that such restraint is not only ethical, but also a matter of good character. It is both unladylike and ungentlemanly to seek one’s own elevation through the diminishment of others.
Not to Be Avaricious
Dogen’s interpretation of this precept in the eighty-third chapter (Jukai) of the Shobogenzo is concise and profound:
“Do not be mean in giving either Dharma or material possessions.”
This understanding points toward generosity in both material life and spiritual life. The bodhisattva shares resources, knowledge, encouragement, and wisdom without clinging to them.
According to the Connected Discourses, Shakyamuni Buddha initially hesitated to teach after his enlightenment because he feared that reality was too subtle and difficult for most people to understand. Then Brahma appeared and urged him to teach. Looking upon the world with compassion, the Buddha saw people as lotus flowers at different stages of growth and decided to share the Dharma for their benefit.
The lesson is clear. One should practice sincerely, teach generously when appropriate, and give freely without attachment to recognition or reward.
True generosity expects nothing in return.
Not to Harbor Ill Will
I feel that this is a special vow.
There is far more to this precept than simply refraining from anger. It encompasses hatred, resentment, prejudice, bitterness, and the many ways human beings separate themselves from one another. It teaches compassion, tolerance, and goodwill toward people of every race, religion, nationality, gender, sexuality, economic background, and social class. We may criticize behaviors, ideas, and actions when necessary, but hatred toward people themselves is deeply unhealthy.
This precept also teaches compassion toward those who have harmed us and those we love. Most of us have experienced difficult relationships and painful encounters. Some of these experiences leave emotional wounds that remain with us for years.
To truly engage this vow requires confronting those wounds directly.
It may require descending into the hidden corners of the mind and facing emotions that have long been buried. Resentment, anger, disappointment, betrayal, and grief often linger beneath the surface of consciousness. The work of this precept is the gradual purification of those emotions through understanding and compassion.
This is not easy.
One may find oneself forgiving parents, siblings, relatives, teachers, clergy, neighbors, classmates, friends, lovers, spouses, abusers, criminals, political opponents, and even enemies. Forgiveness does not mean approving of harmful behavior or abandoning justice. Rather, it means releasing the toxic burden of hatred within oneself.
The purpose is not to excuse wrongdoing.
The purpose is to free the heart.
As resentment is released, compassion becomes possible. Anger gives way to understanding. Division gives way to interconnectedness. The mind becomes less burdened by old injuries and more capable of responding to the world with wisdom.
Empty your cup of bitterness and fill it with samadhi, interconnectedness, and oneness. Then you are prepared to extend goodwill to all beings.
For me, this is one of the deepest and most transformative of all the Bodhisattva Precepts.
Not to Disparage the Three Treasures
In the Three Refuges, the bodhisattva takes refuge in the Three Treasures: the Buddha, the Dharma, and the Sangha. How could one disparage that in which one has taken refuge? To do so would be a contradiction of one’s vows and a corruption of one’s integrity.
To disparage means to denigrate or treat with contempt. In this context, it means speaking or acting in ways that undermine respect for the Buddha, the teachings, or the community of practitioners. It includes disrespect toward the memory of the Buddha, the Bodhisattvas and ancestors, the teachings and practices of Buddhism, and the Sangha itself.
This does not mean that one should abandon critical thinking. Honest inquiry and thoughtful discussion are entirely compatible with Buddhism. However, the Buddha’s teaching on Right Speech reminds us that truth should be expressed with compassion, civility, and respect.
The traditions of Buddhism express this respect in many ways. We bow, prostrate, dedicate merit, chant sutras, and commemorate the Buddha and the ancestors through ritual and remembrance. Yet the deepest expression of respect is not ceremonial.
It is practice.
We sit zazen. We study the sutras and the literature of Zen Buddhism. We learn from teachers, senseis, and roshis. We strive to understand and embody the Dharma in our daily lives.
Likewise, participating in the Dharma means participating in the Sangha. We support one another, contribute to the community, and work toward harmony whenever possible.
To refrain from disparaging the Three Treasures means to honor the Buddha, preserve the Dharma, and support the Sangha. In doing so, we uphold the Bodhisattva Precepts and continue the living tradition of the Buddha Way.
The Precepts as Practice and Realization
One of the distinctive features of Soto Zen is its understanding that practice and realization are not separate.
Eihei Dogen Zenji repeatedly taught that enlightenment is not a distant goal attained after years of effort. Rather, practice itself is the expression of enlightenment. This principle, often summarized as “practice-realization” (shusho ichinyo), lies at the heart of Soto Zen.
The same understanding applies to the Bodhisattva Precepts.
It is easy to regard the precepts as a collection of ethical rules intended to improve behavior. Certainly they serve that purpose. They guide conduct, cultivate virtue, and help reduce suffering. Yet Soto Zen teaches that their significance extends much deeper.
The precepts are not merely rules to be obeyed.
They are expressions of Buddha-nature.
When one refrains from harming others, practices generosity, speaks truthfully, or responds with compassion, one is not merely following instructions. One is expressing the awakened nature that the Buddha realized beneath the Bodhi Tree and that all beings possess inherently.
For this reason, receiving the precepts is traditionally regarded as more than an ethical commitment. It is an affirmation of one’s participation in the Buddha Way.
The ancient Bodhidharma One-Mind Precepts tradition expressed this understanding with remarkable simplicity:
To receive is to transmit.
To transmit is to awaken.
To awaken is true receiving of the precepts.
The precepts are therefore not external obligations imposed from outside oneself. They arise from the same awakened mind that seeks wisdom, practices meditation, and cultivates compassion. They are the activity of awakening in human relationships.
This perspective helps resolve a common misunderstanding. Many practitioners become discouraged when they discover that they cannot perfectly uphold every precept. Human beings remain imperfect. Anger arises. Mistakes occur. Selfishness appears. Even sincere practitioners sometimes fail to embody their highest aspirations.
The purpose of the precepts is not perfectionism.
The purpose is awareness.
When we fall short, the precepts provide an opportunity for reflection rather than condemnation. They reveal where suffering arises and indicate a path toward greater wisdom and compassion. In this way, they function not as instruments of judgment but as tools of awakening.
Dogen often emphasized that Buddhist practice is not founded upon self-improvement in the ordinary sense. The precepts are not merely techniques for becoming a “better person.” They are expressions of a more profound realization: that self and other are not separate. When this truth is glimpsed, compassion arises naturally.
To care for others is to care for oneself. To harm others is ultimately to harm oneself.
The precepts become less a matter of obligation and more a matter of understanding.
This is why the precepts have traditionally been received within the context of refuge, ordination, and community. They are not abstract ethical theories. They are lived commitments practiced within the circumstances of ordinary life.
A practitioner expresses the precepts while caring for family, earning a livelihood, participating in community, facing conflict, confronting injustice, and navigating the countless challenges of human existence. Every interaction becomes an opportunity to embody the Buddha Way.
Seen in this light, the precepts are not separate from zazen. Zazen cultivates awareness. The precepts express that awareness in action. Zazen reveals interdependence. The precepts embody that realization through compassion. Zazen illuminates Buddha-nature. The precepts give Buddha-nature form in daily life.
For Soto Zen practitioners, meditation and ethical conduct are therefore inseparable aspects of a single path.
The Sixteen Bodhisattva Precepts remain vital today because they address enduring aspects of human life. They speak to violence and compassion, greed and generosity, dishonesty and integrity, resentment and forgiveness, isolation and community. Though formulated centuries ago, they continue to illuminate the challenges of the modern world.
Their ultimate purpose is neither obedience nor conformity. Their purpose is awakening.
Through receiving, contemplating, and practicing the precepts, one gradually learns to live with greater wisdom, greater compassion, and greater harmony with all beings. In this sense, the precepts are both the path and the realization. They are both the practice and the expression of awakening itself.
Conclusion
The Sixteen Bodhisattva Precepts are more than ethical guidelines. They are a practical expression of the Buddha Way.
They begin with refuge in Buddha, Dharma, and Sangha. They continue through the cultivation of wisdom, compassion, and wholesome conduct. Ultimately, they point toward the realization that awakening is not separate from everyday life. How we speak, how we work, how we treat other people, how we respond to conflict, and how we care for our communities are all part of Buddhist practice.
Like zazen, the precepts are both practice and realization. They are not merely rules to be obeyed, nor ideals to be admired from a distance. They are invitations to examine our lives honestly and to embody the qualities of a bodhisattva in the world.
No one keeps the precepts perfectly. The purpose is not perfection, but awareness. The precepts serve as mirrors that reveal where wisdom may be strengthened, where compassion may be deepened, and where suffering may be transformed into understanding.
After many years of study and practice, I have come to view the precepts not as restrictions, but as liberating principles. They encourage integrity, generosity, forgiveness, humility, mindfulness, and compassion. They point toward a life lived with greater clarity and purpose.
In the end, the Bodhisattva Precepts are an expression of our interconnectedness. To uphold them is to cultivate harmony within oneself, within one’s community, and within the wider world. In this way, the ancient vows of the bodhisattva remain as relevant today as they were in the time of Dogen Zenji and the generations of practitioners who came before us.
May all beings awaken to their true nature.
May all beings be free from suffering.
May all beings be happy.
