Sadhana Pada 2.46 — Āsana — Steady and Easeful
Āsana in three words — sthira (steady) and sukha (easeful). The whole teaching on posture is a quality, not a catalogue: effortless stability where firmness and ease meet, a body so settled the mind is free.

Commentary
Three words for the third limb
With this sūtra Patañjali reaches the third of the eight limbs, āsana, and disposes of it in three words: sthira, sukham, āsanam — the seat is steady and easeful. There is no catalogue of postures here, no technique, no count of poses, no description of how the limbs are to be arranged. The entire teaching on the body's place in yoga is given as a quality, not a form. Whatever the position, it is āsana when it is at once firm and comfortable; whatever the position, it falls short of āsana when it lacks either firmness or comfort.
The brevity is itself a teaching. After the long ethical discipline of yama and niyama, the reader might expect the physical limb to be elaborated at length, and the later physical cultures that grew under the name yoga did exactly that. Patañjali does the opposite. He gives a definition so spare that it cannot be mistaken for a method, and in doing so he keeps the limb subordinate to its purpose. The body is not the destination of the path but a station along it, and the sūtra's economy keeps it in that proportion.
The word asana itself
The term āsana derives from the verbal root ās, "to sit, to be seated, to remain, to abide." Its primary sense is not "posture" in the modern athletic meaning but "seat" — the place and manner of sitting, and by extension the act of remaining settled. To do āsana, in the root sense, is simply to sit and to stay sat. This etymology quietly governs everything the sūtra means: the limb is about abiding, about a body that can remain, far more than about shaping or stretching the body into difficulty.
Read against its root, the sūtra is almost tautological in the best way — the seat (āsana, the abiding-place) is that in which one can truly abide, steadily and at ease. A position one cannot remain in is, by this measure, not yet a seat at all. The whole later vocabulary of named postures rests on this single primitive sense of sitting and staying.
The two qualities held in tension
The two governing words are held in deliberate tension. Sthira, from the root sthā ("to stand, to stay firm"), means steady, stable, unwavering — the quality of a thing that does not shake and does not move. Sukha means ease, comfort, the absence of strain; its older sense is spatial, a "good axle-hole" or "good space" through which a wheel turns smoothly, and so by extension anything that runs without friction, the opposite of duḥkha, the cramped and grinding "bad space" of suffering. To call a seat sukha is to say it runs true, without binding.
A posture that is steady but rigid fails the test, for it has sthira without sukha; it is held by force and cannot last. A posture that is comfortable but collapsing fails the test equally, for it has sukha without sthira; it has eased itself into slump. Āsana lives exactly where the two meet — effortless stability, alert relaxation, a firmness that does not strain and an ease that does not give way. Neither quality is sacrificed to the other; the achievement is precisely their union in a single seat.
The meditation seat and the body forgotten
The context explains the spareness. In the classical setting āsana means, first of all, the meditation seat: a position the body can hold long and motionless so that it ceases to be a distraction to the mind. The aim is not athletic accomplishment but a body so settled that one forgets it is there. A seat that aches, trembles, or demands constant adjustment keeps pulling the attention back to itself; a seat that is steady and easeful releases the attention to turn inward. The sūtra's measure — firm and comfortable — is therefore exactly the measure of a body that has stopped competing for awareness.
This is why the limb is placed where it is. Patañjali is terse on the physical limbs precisely because, for him, their whole purpose is to prepare a quiet vessel for the inner work that follows — breath, withdrawal, and concentration. The seat is settled so that the breath can be regulated upon it; the breath is regulated so that the senses can be withdrawn; and so the limbs ascend. A noisy, unsettled body would break the sequence at its root, and so the body must first be made quiet.
There is a further reason the seat must be one the body can forget. The deeper limbs ask for duration — concentration and meditation are sustained, not momentary, and the body must be able to hold its position for long stretches without protest. A position that is merely comfortable for a minute but begins to ache in ten is not yet āsana in the full sense; the steadiness and ease must be of a kind that lasts. So the spare definition quietly carries a demand for endurance: the seat must be steady and easeful not for a moment but for as long as the inner work requires, and that durability is itself a fruit of the right marriage of firmness and ease rather than of either alone.
The place of the sutra in the pada
This sūtra sits at a hinge in the second pāda. The earlier portion has laid out the great preliminaries — the kleśas, action and its fruit, the discipline of kriyā-yoga, and the first two limbs of moral restraint and observance. With āsana the focus turns from conduct and inner attitude to the instrument itself, the body, and begins the ascent through the more inward limbs. The two sūtras that follow it (2.47 and 2.48) complete the treatment of posture — naming how the steady ease is reached and what fruit it bears — before the breath is taken up in 2.49. So this sūtra opens a small, tightly built unit of three on the seat alone.
It is striking how much of later yoga grew from this single seed. The vast physical cultures that now carry the name yoga trace, by lineage, to these three words — yet Patañjali's own measure for any posture remains disarmingly simple. Not difficulty, not flexibility, not display: only whether it is steady and easeful at once.
The commentary tradition
The classical commentators read the sūtra's silences as openings rather than gaps. Vyāsa, in the Yoga-Bhāṣya, takes the occasion to list a series of seated positions by name — the lotus, the hero's seat, and others — treating the sūtra not as forbidding specific forms but as setting the quality every form must reach. For Vyāsa the named seats are illustrations of the principle, not a closed canon; the principle remains sthira-sukha.
Vācaspati Miśra, glossing Vyāsa in the Tattva-vaiśāradī, presses the analytic point that the two qualities are co-conditions: neither steadiness alone nor ease alone constitutes āsana, and the seat is defined by their conjunction. Vijñānabhikṣu, reading the sūtra within his broader theistic and Sāṃkhya frame, stresses that the settled seat is valued strictly as preparation for the higher limbs, never as an end in itself — the body is composed so that the inner faculties may be composed.
Bhoja, in his terse and elegant manner, fixes on the economy of the definition, taking the very brevity as a sign that posture is a threshold to be crossed rather than a domain to be mastered. It is worth noticing how the commentators, faced with so spare a sūtra, divide their labor: Vyāsa supplies the concrete examples the sūtra withholds, Vācaspati supplies the analytic precision, Vijñānabhikṣu supplies the purpose, and Bhoja supplies the restraint that warns against over-elaboration. Across these views the consensus holds: posture is defined by a quality, not a form; that quality is the conjunction of steadiness and ease; and the whole serves what lies beyond it. The later physical traditions would build vast edifices upon this base, but the commentarial mainstream keeps returning to the sūtra's own modest measure.
Cross-Tradition Connections
The settled seat across traditions
The principle that the body must be settled before the mind can settle is shared wherever sustained contemplation is practiced. The seated traditions of Buddhism describe the meditation posture in nearly identical terms — the body arranged so that it is both stable and unstrained, neither slack nor tense, a position that can be held without the body calling attention to itself. The Heart Sūtra and the wider Prajñāpāramitā tradition it belongs to assume just such a settled seat as the silent ground of clear seeing; the deep looking it describes presupposes a body that has stopped intruding. Zen's instruction simply to "sit" and the Christian monastic stillness of the body at prayer alike treat the steadied posture as the doorway, not the destination.
Firmness through ease
The balance of firmness and ease is itself a near-universal contemplative insight. The Daoist Tao Te Ching praises exactly this union of opposites — the strength that is supple, the stability found in softness rather than rigidity, the supple tree that survives the storm the stiff tree does not. A posture that is steady through ease rather than through strain is a small embodiment of the Daoist conviction that the yielding outlasts the rigid and the relaxed endures where the forced breaks. The same intuition runs through the martial and somatic arts that grew from Daoist soil, where rootedness and relaxation are taught as one quality, not two.
The body as instrument
The hermetic and Pythagorean schools likewise prized stillness of the body as the gateway to stillness of mind. The Golden Verses of Pythagoras commend quiet self-composure and the calm seat from which reflection and nightly self-examination proceed; the Stoic Enchiridion of Epictetus assumes a composed bearing as the outward face of an undisturbed mind. Across these traditions the body is treated not as an obstacle to be conquered but as an instrument to be settled — and a settled instrument, steady and at ease, is the shared precondition for whatever depth is sought.
Universal Application
The sūtra holds up a balance that reaches far beyond the meditation seat: steadiness and ease belong together. We tend to imagine that to be stable we must be tense, braced, gripping — and that to be at ease we must be loose to the point of collapse. Patañjali quietly denies the opposition. The truest stability is the kind that does not strain, and the truest ease is the kind that does not give way; each, fully realized, includes the other.
This union is a quality worth seeking in any posture a life takes — in work, in relationship, in the way one simply sits and is. To be firmly grounded and yet relaxed, present without rigidity, steady without effort: this is a rare and recognizable poise, and we know it instantly in the few people who carry it. Wherever we find ourselves either braced and brittle or comfortable and slumping, the sūtra points toward the meeting place of the two, where stability and ease are no longer at odds but are two names for one settled way of being.
Modern Application
The posture most of us actually hold
Most people now spend their days in positions that are neither steady nor easeful but the worst of both — slumped yet tense, collapsed at the spine while braced at the neck and shoulders, hunched over screens for hours. The body, far from being a settled vessel, becomes a steady source of low distraction and ache. The sūtra's three words name precisely what such positions lack: the marriage of stable support with genuine ease. We have, in effect, mass-produced the anti-āsana — a way of sitting that is at once strained and slumped.
Difficulty is not the measure
The teaching is also a gentle corrective to a fitness culture that often mistakes difficulty for value. Patañjali's measure for a good seat is not how hard it is or how impressive it looks, but whether it is firm and comfortable enough to be forgotten. A posture that demands constant straining has missed the point as surely as one that has collapsed. The most advanced seat, by this measure, is not the most contorted but the most quietly sustainable — the one the body can rest in rather than perform.
Recovering the quiet body
To find, even occasionally, a position the body can hold without strain and without slump — upright, supported, and at ease — is to recover the simple original intent: a quiet body that no longer competes for the mind's attention. The aim is not a perfect pose but a seat one can forget, so that what sits within it is free to attend to something else.
A test you can apply anywhere
The sūtra also offers a portable test for how one is sitting or standing at any moment: is this position both steady and easeful, or has it tipped into bracing or into collapse? The question can be asked at a desk, in a car, in a waiting room — and the small correction it prompts, toward a support that is firm without strain, is the everyday form of the limb Patañjali names.

Frequently Asked Questions
Does Yoga Sutra 2.46 describe specific yoga poses?
No. The sūtra gives no list of postures at all. It defines āsana entirely by a quality — sthira (steady) and sukha (easeful) — so that any position firm and comfortable at once qualifies, and any position lacking either does not. The named poses of later yoga are elaborations on this single standard, not part of the sūtra itself.
What do sthira and sukha mean?
Sthira means steady, stable, unwavering — from the root sthā, to stand firm. Sukha means ease or comfort, the absence of strain; its old sense is a good, frictionless space, the opposite of duḥkha (cramped suffering). True āsana holds both at once: a firmness that does not strain and an ease that does not collapse.
Why does Patañjali say so little about posture?
Because for him the body's settling is preparation, not destination. The seat is made steady and easeful so it stops distracting the mind, clearing the way for breath-regulation, withdrawal, and concentration. The brevity keeps the physical limb in proportion to its purpose rather than turning it into an end in itself.
Is āsana the same as the physical exercise people call yoga today?
The word is the same and the lineage is real, but the emphasis differs. For Patañjali āsana means, first, a meditation seat the body can hold long and motionless. The athletic, flexibility-focused cultures that now carry the name grew from this seed but go far beyond the sūtra's simple measure of steady ease.
Can steadiness and ease really coexist in one posture?
That coexistence is exactly the point. The sūtra denies that stability requires tension and that comfort requires slump. The steadiest seat is the one held without unnecessary effort, and the easiest is the one that still holds firm — a single poise in which the two qualities are no longer opposed. The next sūtra (2.47) explains how it is reached.
