The Yamas and Niyamas: Ten Ethical Observances for Daily Life

Why ethics comes first

It can seem surprising that a text largely remembered today for meditation and, by extension, physical yoga opens its practical instructions with ethics rather than technique. But Patanjali's structure is deliberate: the yamas and niyamas are the first and second limbs, named before asana, pranayama, or any meditative instruction (Sutra 2.29). The implicit claim is that how a person treats others and themselves shapes, and is shaped by, everything that follows. You do not need to accept every metaphysical claim in the Yoga Sutras to find this ordering useful as a practical starting point. For the full eight-limb structure, see our eight limbs of yoga guide.

The five yamas: restraints toward others (Sutra 2.30)

Ahimsa — non-harming. Often translated simply as non-violence, ahimsa is usually understood as extending beyond physical harm to speech and thought: avoiding cruelty, harsh judgment, and unnecessary damage, toward others, oneself, and often, by extension, animals and the environment. It is listed first and is traditionally treated as the foundation the other yamas support.

Satya — truthfulness. Speaking and living honestly. Classical commentary generally qualifies satya alongside ahimsa: truth that causes needless harm is not considered the point of the practice, so satya is traditionally read together with care, not as an excuse for bluntness.

Asteya — non-stealing. Not taking what is not freely given — materially, but also more broadly understood to include time, credit, attention, or energy that belongs to someone else.

Brahmacharya — right use of vital energy. Classically translated as celibacy or chastity, particularly in monastic contexts; many modern teachers read it more broadly as responsible, non-exploitative use of one's vital and sexual energy, appropriate to one's actual life circumstances rather than a single universal rule. Translators genuinely differ here, and we flag that rather than picking one reading as definitive.

Aparigraha — non-grasping. Not hoarding or clinging to more than one needs, whether possessions, relationships, or outcomes. Often paired conceptually with contentment (santosha, below).

The five niyamas: observances toward oneself (Sutra 2.32)

Saucha — cleanliness. Understood both physically (bodily and environmental cleanliness) and mentally (clarity, freedom from unnecessary clutter of thought).

Santosha — contentment. An attitude of acceptance and ease with present circumstances, distinguished from passivity or complacency; classical commentary frames it as freedom from constant craving for things to be otherwise.

Tapas — disciplined effort. Sometimes translated as austerity or "heat," tapas refers to the sustained effort and self-discipline that practice requires — showing up consistently, including when it is inconvenient.

Svadhyaya — self-study. Study of oneself, one's patterns and tendencies, and traditionally also study of sacred or instructive texts. In a modern context this might mean honest self-reflection, journaling, or reading serious material on practice and philosophy.

Ishvara-pranidhana — surrender to a higher principle. Often translated as devotion or surrender to God, or more broadly to a guiding principle larger than the individual ego. This is one of the more theologically loaded terms in the text, and how it is understood varies significantly between devotional and more secular or philosophical readings of yoga.

Applying the yamas and niyamas without turning them into a checklist

A common mistake is to treat the ten as a rigid moral scorecard, graded daily. Classical commentary generally treats them instead as long-term orientations, cultivated gradually and imperfectly over a lifetime of practice. A useful, honest approach is to pick one or two that feel most relevant right now — perhaps asteya around how you use others' time, or santosha around a specific recurring frustration — and observe them closely for a period of weeks, rather than attempting to perfect all ten simultaneously.

Connection to physical practice

The yamas and niyamas are not typically taught explicitly inside a Mysore-style or led Ashtanga Vinyasa class, but many long-term practitioners find that a demanding physical practice becomes a live laboratory for several of them at once: tapas shows up in the discipline of a six-day practice week, discussed in our Ashtanga every day guide; santosha and ahimsa show up directly in how a student responds to a posture that isn't available yet, discussed in is Ashtanga yoga hard and Ashtanga injuries and safety. Understood this way, the mat becomes one place among many to practice the first two limbs, not a separate activity from them.

A note on adjustments and consent

Because asteya, ahimsa and brahmacharya all touch directly on bodily autonomy and consent, they are relevant to an honest conversation about hands-on adjustments in Ashtanga Vinyasa classes, a subject we address directly and factually in our history of Ashtanga Vinyasa and injuries and safety guides. The yamas give a useful ethical vocabulary for thinking through what consent and non-harm should mean in a teaching relationship, whatever era or lineage that relationship comes from.

Starting small

If ten Sanskrit terms feel like a lot to hold at once, a reasonable starting point is simply this: notice, this week, one place where you could be a little more honest (satya), a little less grasping (aparigraha), or a little more disciplined about something you've been putting off (tapas). The yamas and niyamas are, in the end, meant to be lived rather than memorized.
