Quick Answer
The yamas are the first of Patanjali's eight limbs of yoga -- five ethical restraints forming yoga's moral foundation. They are: ahimsa (non-violence), satya (truthfulness), asteya (non-stealing), brahmacharya (wise use of energy), and aparigraha (non-grasping). They apply to thought, speech, and action, in all circumstances.
Key Takeaways
- The yamas are limb one of Patanjali's eight-limbed yoga path -- the ethical foundation before all physical and meditative practice
- They are restraints (behaviors to avoid), distinguished from the niyamas which are personal observances (behaviors to cultivate)
- Patanjali calls them "great vows" (mahavratam) -- universal, unconditional, applying in all circumstances, to all beings
- Practicing the yamas produces specific psychic effects described in the Yoga Sutras: freedom from hostility, knowledge of past and future, wealth, vitality, and knowledge of previous lives
- Modern application: the yamas are best approached as an ongoing investigation rather than perfect rules

The Yamas in Patanjali's System
Patanjali's Yoga Sutras (c. 400 CE) organize the entire domain of yogic practice into eight progressive limbs (ashtanga). The yamas are the first limb -- and this placement is not arbitrary. The Sutras treat the yamas and niyamas as the ground in which the later practices of posture, breath, sensory withdrawal, and meditation grow. Without ethical grounding, the inner practices either fail to penetrate or, worse, amplify personal dysfunction.
Patanjali describes the yamas as mahavratam -- great vows (Sutra 2.31). They are universal: they apply to all classes of people, all places, all times, and all circumstances. They are not situational ethics but unconditional commitments. The aspiration to universality is what makes them a genuine inner practice rather than merely social convention.
The Five Yamas
- Ahimsa -- non-violence, harmlessness
- Satya -- truthfulness, non-falsehood
- Asteya -- non-stealing
- Brahmacharya -- continence, wise management of vital energy
- Aparigraha -- non-possessiveness, non-grasping
Ahimsa: Non-Violence
Ahimsa (Sanskrit: a = not, himsa = harm) is the first and foundational yama. It is the commitment not to cause harm -- through action, speech, or thought -- to any living being, including oneself.
The primacy of ahimsa reflects a core yogic principle: all aggression directed outward begins as an inner disturbance. The practitioner who has genuinely mastered ahimsa -- who has no residual aggression, fear-reactivity, or contempt in the psyche -- will neither cause harm nor attract it. Patanjali's Sutra 2.35 states: when the yogi is established in non-violence, all enmity ceases in their presence (ante vaira-tyagah).
Ahimsa in modern practice extends beyond the obvious prohibitions:
- In action: Not harming others physically; conscious choices about food, consumption, and environmental impact
- In speech: Avoiding harsh words, contemptuous speech, passive aggression, and criticism that demeans rather than informs
- In thought: The inner dialogue toward self and others; catching violence in the mind before it becomes word or action
- Toward self: Ahimsa includes not harming oneself -- not through self-criticism, through forcing the body beyond its limits, or through addictive behaviors
Ahimsa and Courage
A common misunderstanding: ahimsa as passivity. The Bhagavad Gita -- which contains extensive teaching on ahimsa -- is set in the context of a battle. Arjuna's refusal to fight, Krishna argues, is not ahimsa but cowardice. Genuine ahimsa sometimes requires direct confrontation of harm. The yogi who watches injustice and does nothing to avoid personal discomfort is not practicing ahimsa -- they are practicing avoidance. The quality of inner violence (the motivation) is what the practice addresses.
Satya: Truthfulness
Satya (truth, reality) is the commitment to align speech with reality and intention with speech. It encompasses not lying, not deceiving, not misleading, and not presenting oneself as other than one is.
Patanjali's Sutra 2.36: when the yogi is established in truthfulness, action and its fruits come into perfect alignment (kriya-phala-ashrayatvam). This is interpreted as: the words of a genuine truth-sayer become self-fulfilling -- what they say comes to pass -- because there is no gap between their intention and their expression.
Satya is practiced at several levels:
- External honesty: Not saying what is false; not omitting what is materially relevant; not creating false impressions through technically true statements
- Inner honesty: Not deceiving oneself; acknowledging what is actually present in the psyche rather than projecting an idealized self-image
- The intersection with ahimsa: The Yoga tradition recognizes that satya and ahimsa sometimes conflict. When the truth would cause unnecessary harm, ahimsa takes precedence. The classic formulation: speak what is true, speak what is kind, speak what is helpful -- and when these conflict, proceed in that order.
Asteya: Non-Stealing
Asteya (a = not, steya = stealing) extends well beyond the obvious prohibition against taking physical property. In classical commentary, stealing includes:
- Taking credit for others' work or ideas
- Taking more than one's share of shared resources (food, attention, time)
- Keeping something beyond what was agreed
- Taking others' energy through complaint, manipulation, or dependency
- The mental act of coveting -- internally claiming what belongs to another
Patanjali's Sutra 2.37: when the yogi is established in non-stealing, all wealth approaches (sarva-ratna-upasthanam). This paradox -- that by releasing grasping, one comes to have everything needed -- reflects a psychological truth: the covetous mind experiences scarcity even when surrounded by abundance, while the non-grasping mind experiences sufficiency regardless of external circumstances.
Brahmacharya: Wise Use of Energy
Brahmacharya (brahman = universal reality, charya = moving toward) is traditionally translated as celibacy or sexual continence. In classical Indian monasticism, it referred specifically to abstinence from sexual activity as a means of conserving ojas (vital energy) for spiritual practice.
The broader and more applicable modern interpretation is wise use of vital energy -- neither wasting nor suppressing the life force, but channeling it toward what one values most.
Practice: Brahmacharya in Modern Practice
For monastics and serious renunciates: The classical teaching of sexual celibacy as a complete channeling of vital energy into spiritual practice. This remains valid for those on intensive contemplative paths.
For householders: Sexual energy engaged with integrity, mutuality, and full presence rather than as distraction, compulsion, or escape. The quality of engagement matters as much as the frequency.
More broadly: All vital energy (food, sleep, attention, speech, creative output) managed with awareness -- neither dissipated carelessly nor held so tightly it stagnates. The question brahmacharya asks of any activity: does this support what I am building, or does it drain it?
Patanjali's Sutra 2.38: when the yogi is established in brahmacharya, great vitality is gained (virya-labha). This is the promise of conserved energy: that practices of restraint produce more capacity, not less.
Aparigraha: Non-Possessiveness
Aparigraha (a = not, parigraha = grasping, hoarding) is the practice of releasing attachment to objects, relationships, outcomes, and self-concepts. It is the recognition that holding on to what is impermanent produces suffering, and that releasing the grip allows things to move through life rather than being stored, protected, and eventually lost anyway.
Aparigraha addresses three forms of grasping:
- Accumulation: The compulsion to collect and hoard -- possessions, status, relationships, experiences -- beyond what is genuinely needed or used
- Control: The attempt to hold fixed what is by nature changeable -- people, circumstances, the future
- Identity: The identification with roles, achievements, and self-concepts that must be defended against change
Patanjali's Sutra 2.39: when the yogi is established in non-possessiveness, knowledge of the wherefore of existence arises (janma-kathamta-sambodhah). This is interpreted as: the practitioner who releases grasping gains insight into the purpose and continuity of their existence across lifetimes -- because they are no longer bound to the accumulations of a single life.
The Bhagavad Gita's central teaching -- action without attachment to results (nishkama karma) -- is the practical expression of aparigraha in the domain of work and worldly life. See the Bhagavad Gita guide for this principle in depth.
Practicing the Yamas Today
Practice: A Daily Yama Inquiry
Each evening, take five minutes to review the day through each yama. This is not self-judgment -- it is investigation. Ask simply:
- Ahimsa: Was there harm in my actions, words, or thoughts today? Toward others or myself?
- Satya: Was there a moment today when I was less than honest -- in what I said or how I presented myself?
- Asteya: Did I take more than my share of anything today -- attention, credit, resources, time?
- Brahmacharya: How did I use my energy today? Was it aligned with my values?
- Aparigraha: What was I holding on to today -- an outcome, an opinion, a self-concept -- that I could release?
This practice is not about finding failures to feel bad about. It is about developing the discriminating awareness (viveka) that makes the yamas progressively more natural over time.
The yamas are best understood as a single integrated practice, not five separate rules. They all reduce the same root disturbance: the contraction of awareness into ego-self that grasps what is pleasant, repels what is unpleasant, and treats everything as existing primarily in relation to its own desires. When this contraction loosens -- through honest, non-harming, non-grasping engagement with life -- the inner practices of yoga become naturally effective.
Frequently Asked Questions
What are the yamas in yoga?
The yamas are the first of Patanjali's eight limbs of yoga -- the ethical restraints that form the foundation of yoga practice. There are five: ahimsa (non-violence), satya (truthfulness), asteya (non-stealing), brahmacharya (continence or wise use of energy), and aparigraha (non-possessiveness). They apply to actions, speech, and thought.
What is the difference between yamas and niyamas?
The yamas are ethical restraints -- behaviors to avoid in relation to others and the world. The niyamas are personal observances -- behaviors to cultivate within oneself. Yamas govern outward conduct; niyamas govern inward character. Both are the first two limbs of Patanjali's eight-limbed path and must be established before physical and meditative practices become fully effective.
Do I need to follow the yamas to practice yoga?
In the classical tradition, the yamas are the foundation of yoga practice -- without them, postures and meditation lack ethical grounding and their deeper effects are limited. In modern yoga, they are often practiced as an aspiration rather than a rule: the practitioner works toward non-violence, honesty, and non-grasping as ongoing disciplines rather than perfect achievements.
Beginning Yama Practice
Start with ahimsa -- the first yama is the most foundational. Spend one week paying deliberate attention to every way harm arises in your thoughts, words, and actions. Not to judge it, but to see it clearly. The act of seeing clearly is itself the beginning of transformation. The other yamas grow naturally from this investigation.
