Asana

The Sanskrit āsana is built from √ās — to sit. The literal meaning is seat; by extension, posture, and by further extension, the elaborate physical shapes that contemporary yoga has made nearly synonymous with the word. Each layer of meaning is doing different work; they are worth distinguishing.

In the Yoga Sūtras

Patañjali treats āsana in three verses (Yoga Sūtras 2.46–48):

• 2.46 — sthira-sukham āsanam — the posture is steady and comfortable.
• 2.47 — prayatna-śaithilya-ananta-samāpattibhyām — (achieved) by relaxation of effort and absorption in the infinite.
• 2.48 — tato dvandva-anabhighātaḥ — from this, freedom from the assault of the pairs-of-opposites (heat/cold, pleasure/pain).

That is the entirety of Patañjali on āsana. The posture’s purpose is to not require attention — to provide a stable comfortable base from which the inner limbs (pratyāhāra, dhāraṇā, dhyāna, samādhi) can be pursued. The traditional commentators (Vyāsa, Vācaspati Miśra, Bhoja, Vijñānabhikṣu) list specific seated postures — padmāsana (lotus), vīrāsana (hero), svastikāsana, bhadrāsana — but the Sūtras themselves prescribe none. The principle is functional: steady and comfortable.

In the haṭha texts

The medieval [[hatha-yoga|haṭha tradition]] develops the repertoire considerably. The [[hatha-yoga-pradipika|Haṭha Yoga Pradīpikā]] (c. 15th c., Svātmārāma) names 15 āsanas and gives technical descriptions; among them: siddhāsana (the adept’s seat), padmāsana (lotus), siṃhāsana (lion), bhadrāsana (auspicious), mayūrāsana (peacock — a balancing posture on the hands), kukkuṭāsana (rooster), matsyendrāsana (a seated twist named after the Nāth founder), paścimottānāsana (seated forward fold). The Gheraṇḍa Saṃhitā (c. 17th c.) extends the list to 32. The Śiva Saṃhitā describes 84 — but only four in detail; the figure 84 is symbolic (the canonical count of yogic postures) more than enumerative.

Most haṭha postures are seated, reclining, or inverted; the dynamic standing postures are largely absent. The exception is sūryanamaskāra ([[sun-salutation|sun salutation]]), which has medieval and early-modern antecedents but reaches its now-familiar dynamic-sequence form in the 20th century.

In modern practice

The standing repertoire that organizes contemporary studio yoga — tāḍāsana (mountain), trikoṇāsana (triangle), vīrabhadrāsana I–III (warrior), uttānāsana (standing forward fold), adho mukha śvānāsana (downward-facing dog), utkaṭāsana (chair), the full sūryanamaskāra sequences — was largely synthesized between 1924 and 1940 at the Mysore Palace yoga-śālā under [[t-krishnamacharya|T. Krishnamacharya]]. Krishnamacharya’s Yoga Makaranda (1934) is the first text to present this repertoire systematically; his students — [[bks-iyengar|Iyengar]], [[k-pattabhi-jois|Pattabhi Jois]], Desikachar, Indra Devi — carried distinct lineages of it worldwide.

Mark Singleton’s Yoga Body (2010) and the photographic comparison with Niels Bukh’s Primitive Gymnastics (1922) made the historical synthesis concrete: many of the warrior- and triangle-family postures are visually identical to the Danish gymnast’s primitive exercises. This is not a debunking; it is a description. The modern standing repertoire is a real and valuable practice whose textual genealogy is partly invented — like many other living traditions.

How the same word does three jobs

In contemporary usage, āsana names:

1. A meditation seat — take your āsana, meaning sit down to meditate. The Patañjali sense.
2. A specific posture — do warrior II, the next āsana is triangle. The lineage-and-studio sense.
3. The entire practice category — āsana practice, as in the physical practice as a whole, distinct from prāṇāyāma practice or [[zazen|seated meditation]]. The modern-postural sense.

In texts and conversation the three slip into one another. Awareness of which sense is operating prevents avoidable confusion.

On the sthira-sukham test

The classical functional test — steady and comfortable — remains a useful instrument across all three senses. A modern āsana practice in which the posture has become a struggle, an aesthetic project, or an injury vector has departed from Patañjali’s criterion. The criterion does not require staying small; it requires that whatever shape the body is in, attention rests easily in it. [[bks-iyengar|Iyengar]]‘s mature work — long holds, prop-assisted alignment so the structure is actually stable — is one disciplined recovery of this principle.
