Samadhi Pada 1.6 — The Five: Right Knowledge, Error, Imagination, Sleep, Memory

They are: right knowing, error, conceptual imagining, sleep, and memory.

Naming the five at last

Having declared in the previous sūtra that the turnings of the mind are fivefold and either afflicted or unafflicted, Patañjali now keeps his promise and names them. The whole verse is a single bound compound — pramāṇa-viparyaya-vikalpa-nidrā-smṛtayaḥ — five members fused into one word and resolved by the plural ending -ayaḥ, which silently restates the noun vṛttayaḥ carried over from the preceding line.

This is the economy of the sūtra style at its most characteristic: a list compressed to the bone, every syllable load-bearing, nothing repeated that the reader can supply. The grammar itself enacts the teaching — five distinct movements gathered under one heading, the unity of "mind in motion" expressed as a single word that nonetheless unfolds into five.

That the five are bound into one compound rather than listed separately is itself quietly meaningful. For all their difference, they share a single nature as movements of one mind, and the fused word keeps that shared nature in view even as it distinguishes the members. The reader is meant to hear both at once: five kinds, one churning. It is the same double vision the whole pāda asks for — to discriminate the contents of the mind finely while never losing sight of the fact that all of them are, equally, what must finally come to rest.

Glossing the five members

The members, taken in order, are pramāṇa (right knowing, valid cognition — from pra-mā, "to measure correctly," the faculty that takes the true measure of a thing), viparyaya (error, literally a "turning the wrong way round," mis-cognition), vikalpa (conceptual imagining, the mind's alternative-construction from words alone), nidrā (sleep), and smṛti (memory, from smṛ, "to remember," that which is "borne in mind").

The compound is a dvandva, a coordinative string in which each member stands as an equal — not a hierarchy but an inventory. Read this way, the verse is the table of contents for the next five sūtras (1.7 through 1.11), each of which will take one member and give it a precise definition. To name first and define afterward is itself a method: the mind is shown the whole map before it is walked through any single region of it.

The logic of the order

The ordering is not arbitrary, and the commentarial tradition lingers on it. The first three concern the mind's relation to an object of knowledge. Pramāṇa meets the object as it is; viparyaya meets it as it is not; vikalpa meets no object at all, resting on words alone. So the opening triad runs from full grounding in reality, through partial and false grounding, to no grounding whatsoever — a descending scale of contact with the real.

The last two members, nidrā and smṛti, stand apart: they are states in which ordinary object-cognition is suspended or re-presented. Sleep rests on the experience of absence; memory re-presents an object once experienced but not now present. The structure thus moves from the mind facing the world — true, false, fanciful — to the mind turned upon its own conditions, its blank and its trace.

Seen as a whole, the sequence has a quiet completeness. It accounts for the mind in clear contact with reality, in mistaken contact, in contact with nothing but its own words, in the suspension of contact altogether, and in the recall of a contact now past. Between these five, it is hard to point to a movement of mind that is not located somewhere on the map. The ordering is thus not merely tidy but argumentative: it is laid out so that the reader, running through the list, is led to feel that nothing has been left out — which is exactly the conviction the next move depends on.

The commentary tradition on completeness

The classical commentary in the Yoga-Bhāṣya attributed to Vyāsa makes a point easy to miss and decisive for the whole text: that these five turnings, however different in kind, are alike in being movements of the same citta, the mind-stuff, and alike in needing to be stilled. Vācaspati Miśra, expanding this in his subtle gloss, underscores that the list is meant to be exhaustive — Patañjali is not offering examples but a complete enumeration.

Whatever the mind is found doing, the claim runs, it is doing one of these five. This is an audacious philosophical wager, and the audacity is the point. If the inventory is truly complete, then nirodha, the stilling that yoga is, can be defined with precision as the cessation of exactly these and nothing more. Bhoja, in his Rāja-mārtaṇḍa, reads the verse in the same spirit, treating the five as a tidy and total account of the modifications the practitioner must learn to recognize and quiet.

The wager has a practical edge as well as a philosophical one. A practitioner armed with a complete list knows that nothing arising in the mind falls outside the work; there is no stray content that can claim exemption, no thought that is somehow not a turning and therefore not to be settled. The completeness closes every loophole. It is the difference between a discipline that addresses some of the mind and one that, in principle, addresses all of it — and only the latter could promise the total stillness the second sūtra defines.

Movements, not verdicts

A further subtlety lies in the previous sūtra's qualifier, carried silently into this one: the turnings are kliṣṭa or akliṣṭa, afflicted or unafflicted. The five named here are not, in themselves, sorted into good and bad. Each can run either way. Pramāṇa is the most valuable of the five, yet right knowing pursued in the service of craving is still afflicted; vikalpa is the most groundless, yet a benign imagining that loosens attachment can be unafflicted and even useful on the path.

The list therefore catalogs movements, not verdicts. This matters because it locates the problem yoga addresses not in any particular content of mind but in the fact of movement itself — in the mind's restless turning, whatever direction it turns. The fivefold inventory names the kinds of churning; the prior verse names the two flavors each can carry; and the goal of the text is the stilling of the churning as such.

Why sleep and memory count

That sleep and memory are counted as vṛttis at all is the verse's most consequential move, and it works by contrast. A naïve view treats sleep as the simple absence of mind and memory as a passive storehouse rather than an activity. Patañjali refuses both. By classing dreamless sleep as a turning — a movement whose object is absence — he forecloses the seductive error that the goal of yoga might be a kind of sleep, a blanking-out, an emptiness achieved by simply switching the mind off. And by classing memory as a turning, he marks even the mind's faithful re-presentations of the past as ripples on the lake, not the lake at rest.

The cumulative effect of naming all five is therefore to define, by exclusion, the one state that is none of them: a wakeful stillness in which right knowing, error, imagining, sleep, and memory have all subsided. Sāṃkhya-Yoga metaphysics underwrites this, for the citta is held to be a modification of prakṛti, unconscious nature, borrowing its apparent light from the witnessing puruṣa; every vṛtti is therefore a churning of insentient material, and freedom lies not in any particular churning but in the churning's complete repose. To list the five exhaustively is the necessary preface to silencing them, and that silence — luminous, awake, and beyond all five — is the destination the rest of the pāda will chart.

The taxonomic impulse

The ambition to give a complete inventory of the mind's operations links Patañjali to the great taxonomic projects of contemplative thought. Buddhist Abhidharma offers the most elaborate parallel: where Patañjali names five turnings, the Theravāda Abhidhamma enumerates fifty-two mental factors (cetasikā) arising and ceasing moment by moment, and the Sarvāstivāda lists run longer still. The number differs wildly, but the impulse is identical — to map awareness so thoroughly that nothing in it can hide unexamined. Both traditions hold that liberation requires first seeing exactly what the mind is doing.

Sleep as a state of awareness

The inclusion of sleep and memory alongside perception, error, and imagination shows an unusually wide conception of "mental activity." The Māṇḍūkya Upaniṣad makes the closest Indian comparison, analyzing consciousness through waking (jāgrat), dreaming (svapna), and deep dreamless sleep (suṣupti), and then a fourth, turīya, beyond all three. Like Patañjali, it refuses to treat deep sleep as mere blankness, insisting it is a distinct mode of awareness with its own seedlike, undifferentiated character. Both texts locate the goal beyond the familiar states rather than in any one of them.

Wakeful, not dull

That the silence of yoga is defined by contrast with all five turnings — sleep included — resonates with the Taoist and Zen insistence that true stillness is not dullness or torpor but a wakeful, alert emptiness. The Tao Te Ching's sage is "empty yet inexhaustible," still yet endlessly responsive — not asleep but awake in a way that has passed beyond the ordinary movements of mind. Patañjali's careful enumeration serves the same end: by naming everything the mind ordinarily does, it marks out the one thing it can also do — fall utterly still while remaining luminously awake.

There is a steadying power in simply holding a complete map. To be told that the bewildering activity of the mind reduces to five recognizable kinds — knowing rightly, knowing wrongly, imagining, sleeping, remembering — is to feel inner chaos become navigable. What can be named can be observed, and what can be observed can, in time, be settled. The list itself is a gift of orientation, a way of meeting one's own mind as a known country rather than a fog.

The deeper value is that self-knowledge begins with honest observation rather than judgment. Before we try to change the mind, we are invited simply to watch it and recognize which of the five is underway: this is memory replaying, this is imagination spinning, this is a clear perception, this is the mind dulling toward sleep. That calm, naturalist's attention to one's own inner life is the root of all genuine inner work, and it is available to anyone willing to look. To name what is happening inside us is already to be a little less ruled by it.

1. An ancient cognitive map

Patañjali's complete inventory of the mind's activity anticipates the spirit, if not the detail, of modern cognitive inquiry, which likewise seeks to map perception, error, imagination, sleep, and memory as distinct and analyzable processes. That a treatise of late antiquity and a contemporary field both treat the mind as something to be observed, categorized, and understood — rather than as an impenetrable mystery — is a quiet convergence between ancient contemplation and modern study.

2. The five as a tool of meta-awareness

For everyday use, the list works as a simple tool of meta-awareness, the very skill that mindfulness practice cultivates. Caught in a spiral, a person can pause and ask which of the five is actually happening: Is this memory replaying an old hurt? Imagination spinning a feared future? A genuine perception of what is here, or an error mistaken for fact? The question alone begins to restore a measure of distance from the churning.

3. Naming loosens the grip

Naming the kind of mental movement underway tends to loosen its grip — and Patañjali supplied the categories long before the techniques of labeling and noting were named in the language of therapy. To recognize "this is imagination, not fact," or "this is memory, not the present," is already to stand a little apart from it, no longer fused with the movement but watching it from a step away.
