Yoga — Patañjali's system

Patañjali's Yoga Sūtra takes Sāṅkhya's metaphysics as given and asks a purely practical question: given that consciousness has become entangled in nature, what does one actually do? Its answer occupies 196 aphorisms, and its second sūtra is the most concise definition of yoga ever written.

Take the three sūtras together and the diagnosis is complete in nineteen syllables. Yoga is the stilling of the mind's movements; when they are stilled, the seer rests in itself; at every other moment the seer takes the shape of whatever the mind is doing. Sārūpya — 'having the same form' — is the key word, and it is not a metaphor for distraction. It is Sāṅkhya's error of misidentification, stated as a continuous condition: the witness is not disturbed by the modifications, it is mistaken for them. Which tells you what nirodha must mean. Not the suppression of thought, and certainly not unconsciousness — a stone has no vṛttis and is not liberated. Nirodha is the interruption of the identification, so that the modifications no longer determine what one takes oneself to be.

The two hands of practice

Two, and neither works alone. Abhyāsa is the effort to remain in the settled state; vairāgya is the withdrawal of thirst from what is seen and from what is heard about. Practice without dispassion builds skill in a mind that still wants the world, and the wanting will spend the skill. Dispassion without practice is only a mood. Patañjali then does something a modern manual would not dare: he states the conditions under which practice takes hold, and they are unglamorous.

Three conditions, each excluding a common failure: long duration excludes the intensive retreat that ends; uninterruptedness excludes the practice resumed after gaps; and satkāra — reverent care — excludes the mechanical repetition that runs on without attention. Only when all three hold is the ground firm. It is the most sober sentence in the literature of meditation.

The four pādas

The five kleśas — what actually causes suffering

The order is causal, not alphabetical. Avidyā is called the field in which the other four grow, and Patañjali defines it with unusual care — not as absence of information, but as a positive, active misperception of four specific kinds.

Four inversions, each of which anybody can check against a day of their own experience. And Patañjali adds a detail practitioners find useful: the afflictions exist in four states — dormant, attenuated, intermittent, and fully active. An affliction that is not currently operating has not been removed; it is merely asleep, and it will wake when its object appears. This is why he does not measure progress by how one feels on a good day.

The physician's four questions

The whole second chapter is arranged on the pattern of a diagnosis, and Patañjali states each of its four parts in a separate sūtra. It is the same fourfold form as Gautama's chain and the Buddha's four truths — a shared method of the age.

Read 2.16 twice. Past suffering cannot be avoided; present suffering is already here; only future suffering is available to be prevented. Yoga makes no promise about what has already happened. And 2.17 names the cause in Sāṅkhya's own vocabulary — the conjunction of seer and seen, the lame man and the blind man. Remove the conjunction and the cause is gone; the cessation follows, and Patañjali names it in 2.25 as kaivalya, the aloneness of the seeing power. The means, 2.26 onward, is unbroken discriminative discernment — and the eight limbs are the apparatus for producing it.

The eight limbs

The restraints are not conditional on anything

This is the sūtra that makes Patañjali's ethics unconditional, and each of the four exclusions blocks a specific evasion. Not limited by jāti: 'I do not injure my own people' will not do. Not by place: not merely in the temple. Not by time: not only on holy days. Not by samaya — occasion, convention, professional circumstance: 'except when my office requires it' will not do either. A restraint that admits any of the four is a vrata; one that admits none is a mahāvrata. Nothing in the text limits the great vow to renunciants.

Posture, in Patañjali's own words

A definition by two properties, and a method that is the exact opposite of exertion: loosen the effort, and let attention rest in the boundless. The third sūtra of the set states the result — one is no longer assailed by the pairs of opposites, heat and cold, hunger and thirst. That is the entire treatment of posture. Its purpose is plainly stated by what follows it: prāṇāyāma begins 'when that has been attained', because a body that cannot sit still cannot host a regulated breath, and a breath that cannot be regulated cannot host a still mind.

The last three limbs are one continuous act

Three definitions of one process at three depths, and the grammar tracks the deepening. In 3.1 there is a mind and a place, and an act of binding. In 3.2 the same situation is described as a single unbroken strand of cognition — tatra, 'there', refers back, so nothing new has begun. In 3.3 it is 'that same state', with the sense of being a cognition dropped away, so that only the object shines. The one word that keeps the account honest is iva — 'as though'. The mind does not actually become void of itself; it appears so, because the sense of being a meditator has ceased to arise. Patañjali then names the three together as saṁyama at 3.4, and the rest of the chapter is what saṁyama, directed at one thing after another, yields.

Having spent a chapter describing the powers that saṁyama produces, Patañjali disposes of them in a line, and the reasoning is exact rather than merely pious. A siddhi is an achievement of the outgoing mind. To value it is to be interested in an object again, and interest in objects is precisely the movement that samādhi was stilling. The powers are not condemned as wicked; they are diagnosed as a return of the disease in a form the patient will enjoy.

Patañjali's Īśvara, and what He is for

Read what is claimed and what is not. Īśvara is a puruṣa — a member of the same category as every other conscious self, distinguished only by never having been entangled. He is not called the creator; nothing in the Yoga Sūtra makes Him the maker of the world, and the cosmology remains Sāṅkhya's throughout. What He is called is guru, and the ground given is temporal: since He is unlimited by time, He was available to the first teachers as He is to the last. His function in the system is operational — surrender to Him is listed as a sufficient means of attaining samādhi at 1.23, and again as one of the five observances. Yoga is a theistic system in which God's principal job is to be teachable from.

Kaivalya, and what actually changes

The last sūtra of the text gives two descriptions of the same event and the 'or' between them is not vagueness — it is the whole point. Described from nature's side, something happens: the guṇas run backwards into their unmanifest ground, having no further work to do. Described from consciousness's side, nothing happens at all; the power of awareness simply stands in its own form, as it always did. This is the answer to the sharpest objection against Yoga, which is Sāṅkhya's own conclusion turned into a question: if puruṣa was never bound, what has eight limbs of practice accomplished? Nothing whatever to puruṣa. Everything to citta. Practice is done by the mind, on the mind, and its result is that the mind stops presenting itself as the self. The seer was free before the first sūtra and is free after the last; what has changed is that the mistake is no longer being made.

Where Yoga parts from Sāṅkhya

The tradition pairs the two as theory and practice, and the pairing is fair, but it undersells Patañjali. Sāṅkhya says the knot is a misidentification and that seeing this undoes it. Yoga observes that the mind in which the seeing must occur is itself agitated, and devotes a treatise to the condition of that instrument. It is the difference between knowing that a lens shows things wrongly and grinding it.
