The Restraints — how we meet the world, before we ever meet the mat.

Yama · yama

Root: √yam — “to restrain, to curb, to hold in check” (the same root used for reining in a horse). One-line: the restraints.

“Non-harming, truthfulness, non-stealing, right use of energy, and non-grasping: these are the yamas.”

What is Yama

The first limb — restraint in a shared world

Yama is the first limb of Patañjali's eightfold path, and the word itself tells you what it does: √yam means to restrain, to hold something within bounds — the same verb used for reining in a horse. Where later limbs will ask the practitioner to gather and direct attention, Yama starts one step earlier, with how a person moves through the world in relation to others. It is outward-facing: five restraints governing action, speech, and impulse in a shared world.

Patañjali makes an unusual claim about these five in the very next sūtra (YS II.31): they form a mahāvrata — a “great vow” — that holds regardless of one's class, place, time, or circumstance. Not situational ethics, adjusted for context, but something closer to bedrock. This is part of why Yama opens the path rather than appearing somewhere in the middle: everything that follows — steady posture, regulated breath, one-pointed attention — is far harder to sustain honestly on a foundation of harm, dishonesty, or grasping.

Yama and Niyama are usually read as a pair: Yama restrains what would harm the world around you; Niyama cultivates what nourishes the world within you. Both belong to the bahiraṅga — the “outer-limbed” practices — not because they're superficial, but because they concern conduct and orientation before the more interior work of attention and absorption begins.

The Five Yamas

The Five Yamas

1 · Ahiṃsā
Ahiṃsā
Non-harming

From a- (not) + hiṃsā (injury, harm). The most fundamental of the five, and traditionally read as the ground the other four stand on — not just refraining from violence, but a settledness that changes the emotional weather around a person.

ahiṃsā-pratiṣṭhāyāṃ tat-sannidhau vaira-tyāgaḥ — “in the presence of one grounded in non-harming, hostility itself dissolves.”YS II.35
2 · Satya
Satya
Truthfulness

From sat, “that which is” — truth, or being itself. Speech and action aligned with what's real.

satya-pratiṣṭhāyāṃ kriyā-phala-āśrayatvam — for one established in truth, actions and their results become dependable; word and outcome align.YS II.36
3 · Asteya
Asteya
Non-stealing

From a- (not) + steya (theft). Extends past property to time, credit, attention — anything taken that wasn't freely given.

asteya-pratiṣṭhāyāṃ sarva-ratnopasthānam — all treasures present themselves to one who has stopped grasping at what isn't theirs.YS II.37
4 · Brahmacharya
Brahmacharya
Right use of vital energy

From brahma (the highest, the absolute) + carya (conduct, movement toward). Popularly narrowed to “celibacy,” but its older sense is broader: conduct that moves toward what matters most, rather than dissipating energy in every direction.

brahmacarya-pratiṣṭhāyāṃ vīrya-lābhaḥ — vigour, vitality, is gained.YS II.38
5 · Aparigraha
Aparigraha
Non-grasping

From a- (not) + pari (around) + graha (seizing). Non-possessiveness — taking only what's needed, holding what comes lightly.

aparigraha-sthairye janma-kathaṃtā-sambodhaḥ — steadiness in non-grasping brings insight into the “how and why” of one's own existence.YS II.39

In the Ashtanga Tradition

Restraint as lived practice

Pattabhi Jois's Yoga Mala frames Yama plainly as restraint in one's dealings with the outer world, and spends comparatively little time theorising it — the emphasis in this lineage has always fallen on lived practice over doctrine. In a Mysore room, that plays out concretely: you don't get to compare your practice to your neighbour's (Asteya, Aparigraha), you don't fake a posture you haven't earned (Satya), you don't force a body that isn't ready (Ahiṃsā). The six-day-a-week discipline of the method becomes the classroom for Yama, whether or not it's ever named aloud.

Practising It

A running question, returned to daily

Off the mat, Yama shows up less as a rulebook and more as a running question: does this action, this word, cost someone else something they didn't agree to give? Ahiṃsā asks it of the body and of others; Satya asks it of speech; Asteya of time and credit; Brahmacharya of energy; Aparigraha of possessions and outcomes. None of the five are meant to be perfected before starting — they're the practice itself, returned to daily.
