Aṣṭāṅga: The Eight Limbs
A comparative synthesis of the eight-limbed path across the classical texts: from Patañjali's aṣṭāṅga to the seven instruments of Gheraṇḍa and the four chapters of Haṭha Yoga.
Yogaṅgānuṣṭhānād aśuddhikṣaye jñānadīptir āvivekakhyāteḥ — YS 2.28
“By the sustained practice of the limbs of yoga, impurity is destroyed and the light of knowledge arises, leading to discriminative discernment.”
The aṣṭāṅga, the eight-limbed system, constitutes the most influential structural framework in the history of yoga. While Patañjali’s Yoga Sūtra (circa 400 CE) gives us the classical enumeration, the later haṭha texts rearrange, expand, and occasionally subordinate these limbs to serve different soteriological priorities. This synthesis traces the eight-limbed path across four seminal works, noting not only what each text preserves but what it transforms.
I. Patañjali: The Classical Aṣṭāṅga
In Yoga Sūtra 2.28–3.8, Patañjali presents yoga as a progressive eight-limbed discipline (aṣṭāṅga-yoga), where each limb prepares the ground for the next:
| # | Aṅga | Sūtra | Core Practice |
|---|---|---|---|
| 1 | **[[glosario/yama | Yama]]** | YS 2.30 |
| 2 | **[[glosario/niyama | Niyama]]** | YS 2.32 |
| 3 | **[[glosario/asana | Āsana]]** | YS 2.46–48 |
| 4 | **[[glosario/pranayama | Prāṇāyāma]]** | YS 2.49–53 |
| 5 | **[[glosario/pratyahara | Pratyāhāra]]** | YS 2.54–55 |
| 6 | **[[glosario/dharana | Dhāraṇā]]** | YS 3.1 |
| 7 | **[[glosario/dhyana | Dhyāna]]** | YS 3.2 |
| 8 | **[[glosario/samadhi | Samādhi]]** | YS 3.3 |
Patañjali’s innovation lies in the sequential architecture. Yama and niyama constitute the ethical foundation; āsana and prāṇāyāma the somatic preparation; pratyāhāra the decisive transition inward; and dhāraṇā, dhyāna, and samādhi the three stages of saṃyama (integrated meditative absorption).
The bāhya-aṅga (external limbs) are yama, niyama, āsana, and prāṇāyāma (YS 2.29). Pratyāhāra marks the threshold; the antara-aṅga (internal limbs) begin with dhāraṇā. This external/internal division shapes every subsequent text, even when the specific practices shift.
II. Haṭha Yoga Pradīpikā: Four Chapters, Four Instruments
The Haṭha Yoga Pradīpikā (15th century, Svātmārāma) departs substantially from Patañjali’s linear model. Here the body, ethics — becomes the primary instrument, and the four chapters map organically onto a reduced set of aṅgas:
Chapter 1: Āsana (verses 10–66)
- Fifteen postures are described, with śīrṣāsana (headstand), sarvāṅgāsana (shoulderstand), and padmāsana (lotus) given preeminence.
- The claim is explicit: āsana is the first practice; without it, no further progress is possible (HYP 1.10).
Chapter 2: Prāṇāyāma and Ṣaṭkarma (verses 1–78)
- Nāḍī śuddhi (purification of the subtle channels) precedes prāṇāyāma.
- The eight kumbhakas (breath retentions) are named and described.
- Ṣaṭkarma (the six cleansing acts) occupy a significant portion, reflecting haṭha’s somatic emphasis.
Chapter 3: Mudrā and Bandha (verses 1–130)
- Ten mudrās (seals) including mahāmudrā, mahābandha, khecarī, and viparīta karaṇī.
- These are grouped under the heading of practices that awaken kuṇḍalinī and reverse the flow of bindu (vital fluid).
Chapter 4: Samādhi (verses 1–114)
- The chapter opens with the statement that rāja-yoga and haṭha-yoga are inseparable (HYP 4.1–4).
- The culminating states — manomanī, unmanī, amarī — are described without the intermediate dhāraṇā/dhyāna framework.
What the HYP omits: Yama and niyama receive minimal treatment (a single verse, HYP 1.17, mentions the ten restraints). Pratyāhāra is addressed briefly (HYP 2.68–72). The soteriological goal is not kaivalya (Patañjali’s isolation of pure consciousness) but the awakening of kuṇḍalinī and the attainment of jīvanmukti (liberation while living).
III. Gheraṇḍa Saṃhitā: Seven Instruments (Sapta Karaṇāni)
The Gheraṇḍa Saṃhitā (17th–18th century) proposes a restructured seven-limbed system (sapta karaṇāni), explicitly redefining the aṅgas as instruments (karaṇa) rather than hierarchical stages:
Śodhanaṃ dṛḍhatā caiva sthiratvāvaraṇaṃ dhṛtiḥ / Pratyāhāras tu dhyānaṃ ca samādhiś caiva saptamaḥ // GS 1.4
| # | Karaṇa | Correspondence | Description |
|---|---|---|---|
| 1 | Śodhana | Ṣaṭkarma | The six cleansing acts: dhauti, basti, neti, trāṭaka, naulī, kapālabhāti (GS 1.8–13) |
| 2 | Dṛḍhatā | Āsana | Eighty-four postures; Gheraṇḍa emphasizes mastery of padmāsana, bhadrāsana, and vajrāsana (GS 2.1–9) |
| 3 | Sthiratva | Mudrā | Twenty-five seals including mahāmudrā and khecarī, stabilizing the body and mind (GS 3.1–75) |
| 4 | Āvaraṇa | Pratyāhāra | Withdrawing the senses from their objects through the pañca-dhāraṇā (five concentrations on the elements) (GS 4.1–8) |
| 5 | Dhṛti | Dhāraṇā | Fixing the citta on specific centers (navel, heart, throat, etc.) (GS 5.1–11) |
| 6 | Dhyāna | Dhyāna | Meditative absorption with form (saguṇa) and without form (nirguṇa) (GS 6.1–8) |
| 7 | Samādhi | Samādhi | The ghaṭa-stha-yoga, state where jīvātman and paramātman unite like water and milk (GS 7.1–12) |
Gheraṇḍa’s innovation is the elevation of śodhana (purification) to the first instrument and the inclusion of mudrā as an independent limb. The ethical foundations (yama, niyama) are entirely absent from the formal structure, though they may be implied as prerequisites. The text’s name for its system — ghaṭa-stha-yoga, “yoga of the pot” (the body as vessel) — highlight.
IV. Śiva Saṃhitā: An Alternative Architecture
The Śiva Saṃhitā (17th century, possibly earlier) presents a different organizational logic, one closer to tantric cosmology than to Patañjali’s linear model:
Chapter 1: The subtle body and the pañca-mahābhūta (five elements) within it.
Chapter 2: The ṣaṭ-cakra (six cakras) and the three granthis (knots), with śaktī-cālana (raising kuṇḍalinī) as the core practice.
Chapter 3: The fourfold practice of mantra-yoga, haṭha-yoga, laya-yoga, and rāja-yoga.
Chapter 4: Detailed description of prāṇāyāma, mudrā, and dhyāna.
Chapter 5: The highest state: union with Śiva.
Unlike the Gheraṇḍa Saṃhitā, the Śiva Saṃhitā does not enumerate discrete limbs. Instead, it presents yoga as a map of the subtle body, cakras, nāḍīs, and granthis — through which the practitioner must navigate. The aṅgas are absorbed into this cartography: āsana prepares the vessel, prāṇāyāma moves the energy, mudrā seals it in place, and dhyāna directs it upward through the cakras. The text’s famous declaration — “Only rāja-yoga gives liberation; the others are merely preparatory” (SS 3.21) — reveals a hierarchical classification absent from Patañjali’s integrated model.
V. Convergences
Despite their divergent structures, all four texts converge on several non-negotiable elements:
-
The body as instrument. Even Patañjali, whose soteriology prioritizes kaivalya (isolation of consciousness from matter), acknowledges that āsana and prāṇāyāma prepare the ground for meditation. The haṭha texts simply extend this premise, making the body the primary arena of practice.
-
Breath as bridge. Prāṇāyāma appears in every system, positioned as the decisive practice that links the external (body, senses) to the internal (mind, consciousness). Its placement varies — second limb in Patañjali, fourth in Gheraṇḍa. its centrality does not.
-
The threshold of pratyāhāra. Every text marks a transition point where the practitioner turns inward. Whether called pratyāhāra (Patañjali, HYP), āvaraṇa (Gheraṇḍa), or simply the passage from lower to higher cakras (Śiva Saṃhitā), this withdrawal remains structurally essential.
-
Samādhi as terminus. All paths converge on absorption — whether described as Patañjali’s nirbīja samādhi (seedless absorption), Svātmārāma’s unmanī (mindless state), or Gheraṇḍa’s ghaṭa-stha (union in the vessel). The names differ; the experience does not.

VII. Integrated Synthesis
The aṣṭāṅga framework is not a static monument but a living architecture, adapted by each tradition to its particular soteriology. To read Patañjali’s eight limbs as the “correct” version and the haṭha texts as deviations is to misunderstand the history of yoga. Each text responds to a different question:
-
Patañjali asks: How does consciousness free itself from the fluctuations of the mind? His answer is a systematic, ethical, and progressively internalizing discipline.
-
Svātmārāma asks: How does the practitioner use the body to force the emergence of liberating knowledge? His answer prioritizes somatic technologies — āsana, prāṇāyāma, mudrā — that work directly on the subtle body.
-
Gheraṇḍa asks: What are the necessary instruments for purifying and transforming the bodily vessel? His answer restructures the limbs around purification (śodhana) and stabilization (dṛḍhatā), treating each instrument as parallel rather than sequential.
-
Śiva asks: How does the yogin ascend through the cakras to unite with the divine? His answer dissolves the discrete limbs into a cartography of the subtle body.
For the contemporary practitioner, the lesson is twofold. First, the classical eight-limbed path preserves an irreplaceable ethical and contemplative structure: no amount of āsana or prāṇāyāma can substitute for yama, niyama, and the systematic cultivation of saṃyama. Second, the haṭha innovations — śodhana, mudrā, kuṇḍalinī — address dimensions of embodied experience that Patañjali’s concise sūtras merely gesture toward. A complete practice draws from both streams: the ethical rigor of the Yoga Sūtra and the somatic precision of the haṭha corpus.
The aṅgas are not rungs on a ladder to be left behind but limbs of a body that must all be developed. As Patañjali reminds us, the practice of one limb illuminates the others (YS 2.28). In the haṭha texts, that interdependence becomes literal: the body is the path, and every practice — whether cleansing, postural, respiratory, or meditative — is a limb of the same organic whole.
