yogāṅgānuṣṭhānād aśuddhi-kṣaye jñāna-dīptir ā viveka-khyāteḥ "Through the practice of the limbs of yoga, impurity is worn away, and the light of knowing grows until discernment is complete." — Patañjali, Yoga Sūtra 2.28

Patañjali did not offer eight limbs as a menu. He offered them as a purification. The sūtra above, placed one line before he names the limbs, tells you what the whole structure is for: not flexibility, not calm as a lifestyle product, but the steady wearing away of whatever clouds the mind's ability to see clearly.

That framing matters because the word Ashtanga has been quietly rewritten. Read the eight limbs as Patañjali set them, and you are reading one of the most precise maps of the human mind ever compressed into a few dozen lines. Read them the way most of the internet does, and you get a workout with Sanskrit labels.

This page sets out all eight parts of Aṣṭāṅga Yoga — what each one is, what the text actually says about it, and how the same map runs through Ayurveda's own understanding of health.

Two Ashtangas share one name, and only one is Patañjali's

Search for "Ashtanga yoga" and much of what comes back is a fast, flowing sequence of postures linked to breath — a twentieth-century system known as Ashtanga Vinyasa. It is a legitimate physical practice. It is not what this word originally named.

Aṣṭāṅga is simply aṣṭa (eight) + aṅga (limb). Patañjali lists them in a single line:

yama-niyamāsana-prāṇāyāma-pratyāhāra-dhāraṇā-dhyāna-samādhayo 'ṣṭāv aṅgāni — Yoga Sūtra 2.29

Restraint, observance, posture, breath regulation, withdrawal of the senses, concentration, meditation, absorption. Eight. Of these, exactly one — āsana — is a posture. When a single limb is mistaken for the whole body, the body of the practice goes missing.

That is the confusion this page exists to correct. For the broader case of what yoga is and is not, see Understanding Yoga.

A limb is not a rung — but the limbs still have an order

Patañjali chose the word aṅga, limb, not sopāna, step. Limbs grow together. A child's arms do not wait for its legs to finish. In the same way, a person practising āsana is already, in a small way, practising restraint and attention.

And yet the text is clear that the limbs are not interchangeable. In the third chapter, Patañjali divides them:

Bahiraṅga — the outer five: yama, niyama, āsana, prāṇāyāma, pratyāhāra.
Antaraṅga — the inner three: dhāraṇā, dhyāna, samādhi. (trayam antaraṅgaṃ pūrvebhyaḥ — "these three are inner, relative to the ones before," Yoga Sūtra 3.7)

The outer limbs prepare the ground. The inner limbs are what grows on it. Attempting deep concentration with an undisciplined life, an unsteady body and a scattered breath is like trying to hold a candle flame still in a storm. This is not a moral judgement; it is a mechanical one.

Here is the full map before we walk it.

#	Limb	Literal sense	What it governs	Group
1	Yama	Restraint	Conduct toward others	Outer
2	Niyama	Observance	Conduct toward oneself	Outer
3	Āsana	Seat, posture	The body	Outer
4	Prāṇāyāma	Regulation of breath	The breath	Outer
5	Pratyāhāra	Drawing back	The senses	Outer (the hinge)
6	Dhāraṇā	Holding	Attention	Inner
7	Dhyāna	Meditation	Sustained attention	Inner
8	Samādhi	Absorption	Awareness itself	Inner

The outer five: building a life the mind can rest in

1. Yama — conduct toward others is the first discipline, not the last

Patañjali names five restraints (Yoga Sūtra 2.30): ahiṃsā (non-harming), satya (truthfulness), asteya (non-stealing), brahmacarya (restraint of the senses' appetites), and aparigraha (non-grasping).

Then he says something easily skipped: these become a mahāvrata, a great vow, when they are kept regardless of birth, place, time or circumstance (2.31). The yamas are not etiquette that applies when convenient. They are the minimum condition under which a mind can settle — because a mind that is harming, deceiving or grasping is a mind that is constantly defending itself.

Ahiṃsā comes first for a reason. Everything that follows — including how you treat your own body on the mat — is measured against it.

2. Niyama — conduct toward oneself

The five observances (Yoga Sūtra 2.32): śauca (cleanliness, of body and of mind), santoṣa (contentment), tapas (disciplined effort), svādhyāya (self-study and study of the texts), and īśvara-praṇidhāna (surrender to something larger than the self).

Where the yamas govern what you do to the world, the niyamas govern what you do to yourself. Notice that contentment and disciplined effort sit side by side. Patañjali does not ask you to choose between accepting yourself and working on yourself. He asks for both at once.

3. Āsana — steadiness and ease, not difficulty

The entire definition of āsana in the Yoga Sūtra is three words:

sthira-sukham āsanam — "Posture is that which is steady and easeful." (2.46)

Not twisted. Not heated. Not advanced. Steady (sthira) and at ease (sukha). Patañjali adds that this comes through the relaxing of effort and the mind resting in the boundless (2.47), and that its fruit is freedom from being thrown about by opposites such as heat and cold (2.48).

The original purpose of āsana was to give the body a seat that would not interrupt the mind. That one fact reframes every modern debate about which pose is "better." A pose that strains you has stopped being āsana in Patañjali's sense. For how āsana differs from exercise, see Difference between Yoga Āsanas and Physical Exercise.

4. Prāṇāyāma — the breath is where body and mind meet

Prāṇāyāma, says Patañjali, is the regulation of the movement of inhalation and exhalation, once posture is established (2.49). The sequencing is explicit: breath work follows a steady seat, not the other way round.

The breath is the one bodily function that runs on its own yet can also be taken under voluntary control. That makes it a bridge. Change the breath and the mind follows; disturb the mind and the breath shows it first. Sukhayu's Prāṇāyāma page covers the classical techniques, their Ayurvedic framing and their precautions in detail.

5. Pratyāhāra — the hinge between the outer and inner limbs

Pratyāhāra is the drawing back of the senses from their objects, so that they follow the mind's own inward direction (2.54). Patañjali places it last among the outer limbs, and that placement is the whole point: it is the hinge. Everything before it is practised in relation to the world. Everything after it is practised within.

The senses are not the enemy. They warn us of smoke, show us a sunset, carry another person's voice to us. The problem is direction. Ordinarily the senses lead and the mind follows. Pratyāhāra reverses that: the mind leads, and the senses are allowed to rest. It is not shutting perception off. It is taking the steering wheel back.

The inner three: one movement of attention, deepening

6. Dhāraṇā — attention held in one place

Dhāraṇā, from the root dhṛ, "to hold," is the binding of the mind to a single place (3.1) — a point in the body, the breath, a sound, a flame. The mind will wander. Dhāraṇā is the act of returning it, again and again, without irritation.

7. Dhyāna — attention that no longer needs to be held

When that holding becomes an unbroken flow toward the same object, it is dhyāna (3.2). The difference between concentration and meditation is not the object; it is the effort. In dhāraṇā you keep bringing the mind back. In dhyāna it no longer leaves. Sukhayu's older Meditation page offers an introduction to the practice.

8. Samādhi — when the observer drops out of the picture

In samādhi, only the object shines forth, as though the mind were empty of its own form (3.3). The sense of "I am meditating on this" falls away, and what remains is the thing itself, fully known.

This is not unconsciousness, and it is not a mood. It is clarity without the noise of self-reference. Patañjali also notes that dhāraṇā, dhyāna and samādhi practised together on one object are called saṃyama (3.4) — one deepening movement of attention, not three separate techniques.

Where Ayurveda reads the same map

None of this is foreign to Ayurveda. The two disciplines grew up side by side, and Charaka uses the language of yoga directly — in the first chapter of Śārīra Sthāna he describes yoga as the means that sets liberation in motion, and as the state in which suffering ceases. The overlap runs deeper than shared vocabulary.

Yama and niyama have an Ayurvedic twin: sadvṛtta. In Sūtra Sthāna, Chapter 8, Charaka lays out a code of right conduct — truthfulness, self-restraint, respect, cleanliness, measured speech, measured appetite — as a condition of health, not merely of virtue. In his list of foremost things (Sūtra Sthāna, Chapter 25), he places ahiṃsā at the head of all that sustains life. A physician and a yogi, writing from different directions, arrive at the same first principle.

Pratyāhāra answers one of Ayurveda's three root causes of disease. Charaka names asātmya indriyārtha saṃyoga — the unwholesome contact of the senses with their objects, whether by excess, deficiency or misuse — as a primary cause of illness (Sūtra Sthāna, Chapter 11). Pratyāhāra is the trained capacity to regulate exactly that contact. What yoga calls a limb, Ayurveda recognises as prevention.

Ayurveda's own mind therapy uses the same move. Charaka defines Sattvāvajaya as the restraint of the mind from unwholesome objects (Sūtra Sthāna, Chapter 11) — structurally the same gesture as pratyāhāra, placed inside a system of treatment. We explore this connection, and the role of sattva, rajas and tamas, in Understanding Yoga.

Prāṇāyāma meets prāṇa. Ayurveda's account of Vāta — and of prāṇa vāyu as its seat in the chest and head — gives the breath a physiological weight that yoga describes from the inside.

The traditions do not borrow from each other. They look at the same human being and find the same structure.

How the limbs enter treatment at Sukhayu Ayurved

We do not prescribe "a yoga package." We do not sell packages. We treat diagnoses. Where yoga enters a patient's treatment, it enters as one part of a plan built around that patient's condition — and the order of the limbs becomes a clinical principle, not only a philosophical one.

The clearest example is spine care. In our 3P Program for disc problems — Purification, Pacification, Posture Correction — customised āsanas form part of the third dimension, Posture Correction, alongside postural and ergonomic training and Marma therapy. But āsana begins only when the musculature has regained enough flexibility to receive it, on the physician's judgement and never on a fixed schedule. Āsana on rigid, inflamed muscle can aggravate a disc problem. That is sthira-sukham read clinically: a posture that cannot be held steadily and with ease is not yet the right posture for that body. We explain why the order matters in Why Yoga Can Make Your Sciatica Worse.

The same logic holds across the limbs. Breath work is taught when the body can sit for it. Attention practices are taught when the breath can support them. Nothing is forced, because forcing is the opposite of what the text asks for.

Yoga at Sukhayu is complementary to medical care, never a replacement for it. If you are under treatment for any condition, continue to follow your prescribing physician's advice.

A short pratyāhāra practice: Ṣaṇmukhī, the six-gated seal

Haṭhayoga texts describe Ṣaṇmukhī mudrā — closing the six gates of the face — as a classical aid to drawing the senses inward. It is simple, and it shows in a few breaths what pratyāhāra feels like. For more on hand gestures in the yogic tradition, see Mudrā.

Sit steadily with the spine upright — on the floor or on a firm chair. Relax the shoulders.
Close the gates. Gently place the thumbs over the ear flaps, the index fingers over the closed eyelids, the middle fingers beside the nostrils, the ring fingers above the upper lip and the little fingers below the lower lip. The touch should be light — closure, not pressure on the eyes.
Breathe naturally through the nose, easing the middle fingers away from the nostrils as needed. Let attention rest on the breath, or on the quiet inner sound that becomes noticeable when the ears are closed.
Stay for five to ten breaths, then lower the hands, keep the eyes closed for a moment, and notice the stillness before returning to the room.

Precautions: Do not hold the breath, and never press on the eyeballs. Stop if you feel dizzy, anxious or uncomfortable. If you have an eye condition, a heart condition, uncontrolled blood pressure, or are pregnant, learn any breath or sense-withdrawal practice under a qualified teacher first.

Cure is divine. Treatment is possible.
