The 5 vrittis are the heart of Patanjali’s diagnosis of the mind. In Yoga Sutra 1.2, he tells us that yoga is the cessation of the fluctuations of the mind (chitta vritti nirodhah) — and four sutras later, in 1.6, he names them: pramana, viparyaya, vikalpa, nidra, and smriti. Understanding these five categories transforms abstract philosophy into a precise map you can apply on the mat, in meditation, and in daily life. This guide walks through each vritti, its Sanskrit meaning, and how to recognise it as it arises.
Before turning to the five vrittis in Sutra 1.6, it is worth sitting briefly with the doorway verse atha yoga anushasanam in Sutra 1.1 — the opening line that frames the whole text.
What Are the Vrittis? The Mind in Patanjali’s System
The Sanskrit word vritti literally means “to turn,” “to whirl,” or “to revolve.” In the Yoga Sutras, Patanjali uses it to describe the modifications, fluctuations, or whirlpools of consciousness that move through the field of awareness. Your mind is rarely still; it churns through perceptions, memories, fantasies, doubts, and dreams. Each of these movements is a vritti.
This framework is essential to yoga because Patanjali defines the goal of practice as chitta vritti nirodhah — the stilling of these fluctuations. To still something, you first have to see it clearly. That is exactly what sutras 1.5 and 1.6 do: they categorise the entire range of mental activity into five precise types so that the practitioner can identify, observe, and ultimately quieten them.
If you are new to this layer of yoga philosophy, it may help to first read our breakdown of Yoga Sutra 1.2, which establishes the definition of yoga that sutra 1.6 unpacks. For a wider map of where this fits in Patanjali’s eight-fold system, see our guide to the eight limbs of yoga.
Yoga Sutra 1.6: Pancatayyah — The Five Fluctuations
The sutra itself is famously concise. In Sanskrit, it reads:
Pramana viparyaya vikalpa nidra smritayah — Yoga Sutra 1.6
The fluctuations of the mind are five: valid cognition, misperception, imagination, sleep, and memory.
The preceding sutra (1.5) adds an important nuance: each of these vrittis can be either klishta (afflicted, causing suffering) or aklishta (unafflicted, conducive to liberation). The vrittis themselves are not the enemy. The question is whether they bind you or free you, and the answer depends on your relationship to them.
1. Pramana — Valid Cognition
Pramana is right or valid knowledge: the mental activity that corresponds accurately to reality. When you look across a room and correctly identify a chair as a chair, that is pramana. It is the vritti most aligned with truth, and the one most likely to be aklishta.
The Three Pramanas
Patanjali subdivides pramana into three sources of valid cognition:
- Pratyaksha — direct perception through the senses, the most immediate form of knowing.
- Anumana — inference, the reasoning by which you conclude there is fire when you see smoke.
- Agama — reliable testimony from a trustworthy source, such as scripture or a teacher of integrity.
Even pramana, however, is still a vritti. The practitioner’s task is not to abolish correct knowledge but to recognise that even truthful thought is a movement in the mind, distinct from the silent witness behind it.
2. Viparyaya — Misperception
Viparyaya is false or mistaken knowledge: cognition that takes one thing for another. The classic Indian example is mistaking a coiled rope on the ground for a snake at dusk. The fear is real, the heartbeat is real, but the perception is entirely wrong.
Viparyaya is intimately connected to avidya, the root klesha of ignorance. Our guide to avidya as the first klesha explores this in depth — viparyaya is one of the ways avidya expresses itself in everyday cognition. Mistaking the impermanent for the permanent, or the ego for the Self, is viparyaya operating at the deepest existential level.
On the mat, viparyaya might show up as the conviction that you “can’t do” a posture, when in reality the body is simply unfamiliar with the shape. In relationships, it appears as projection: reading into a friend’s silence a meaning they never intended. Naming the vritti is the first step in releasing it.
3. Vikalpa — Imagination and Conceptual Knowledge
Vikalpa is verbal or conceptual knowledge that has no real object behind it. Patanjali defines it as cognition that follows from words but does not correspond to any actual thing. When you read about a unicorn, your mind forms an image, but no unicorn exists. That mental construction is vikalpa.
Vikalpa includes imagination, fantasy, hypothesis, abstraction, and the entire realm of conceptual thought that hovers above lived reality. Like the other vrittis, it can be klishta or aklishta. Daydreaming yourself into anxious future scenarios is klishta vikalpa; visualising a peaceful breath or rehearsing a kind response before a difficult conversation is aklishta vikalpa.
In meditation, vikalpa is often the loudest vritti. The mental commentary, the internal narration, the “what if” stream — all of it is vikalpa colouring the silence. Recognising thoughts as constructions, not facts, loosens their grip.
4. Nidra — Sleep
It can be surprising that Patanjali counts nidra, sleep, as a vritti. Sleep feels like the absence of mental activity, not a movement of it. But in yogic psychology, sleep is the cognition of nothingness — a specific mental state with its own quality. When you wake and report that you “slept well,” you are remembering an experience of inertia or emptiness, which means awareness was present in some subtle form, registering that state.
Sleep can be klishta — heavy, dulling, escapist — or aklishta — restorative, regulating, conducive to clarity on waking. The yogic practice of yoga nidra uses this insight directly, training the practitioner to remain aware at the threshold of sleep so that the nidra state itself becomes a vehicle for insight rather than oblivion.5. Smriti — Memory
Smriti is memory: the retention and re-presentation of previously experienced objects. Every time you recall a face, a phrase, a flavour, or an emotion from the past, smriti is at work. It is the storehouse from which the other vrittis often draw their material.
Memory is also where the samskaras — the latent impressions left by past experiences — are stored. Smriti is therefore not a neutral playback system. It is colored by attachment (raga), aversion (dvesha), and the other kleshas, which is why the same event can be remembered very differently by two people who lived through it together.
Aklishta smriti is the memory that supports learning, gratitude, and the recollection of teachings on the path. Klishta smriti is the memory that traps you in rumination, regret, or the rehearsal of old grievances. The vritti is the same; the relationship to it is what differs.
Klishta vs Aklishta: Why the Vrittis Aren’t All Bad
One of the most common misreadings of Patanjali is to treat the vrittis as enemies to be eliminated. Sutra 1.5 makes clear that this is not the case. Each vritti carries the potential to bind or to liberate. Right knowledge, when clung to as identity, becomes a subtle form of suffering. Imagination, when used skilfully, becomes a doorway into dharana (concentration) and dhyana (meditation).
The afflicted vrittis are those entangled with the five kleshas: ignorance, ego, attachment, aversion, and fear of death. The unafflicted vrittis are those touched by discernment (viveka), dispassion (vairagya), and steady practice (abhyasa). The same mental movement can be either, depending on what is happening behind it.
How to Witness the Vrittis: Practical Application
Theory is only useful when it sharpens attention. The next time you sit in meditation or move through a flow, try labelling the vritti as it arises. A racing recap of yesterday’s conversation? Smriti. A vivid imagined argument with your boss? Vikalpa. The conviction that the discomfort in your hip means something is torn? Probably viparyaya. A genuine sensory observation of the breath at the nostrils? Pramana. The heavy fog of dozing off in savasana? Nidra.
The act of naming creates a small but crucial gap between you and the vritti. You are no longer identified with the thought; you are the awareness noticing it. Patanjali’s term for this stable witnessing is drashtuh svarupe avasthanam — “the seer abides in their own true nature” (Sutra 1.3). That is the fruit of recognising the vrittis: not their abolition, but the discovery of the ground on which they appear and dissolve.
Pair this contemplation with breath practice. Steady pranayama settles the nervous system enough that the vrittis slow down and become visible. Even a short daily sit, with the five categories held lightly in mind, can transform an otherwise abstract sutra into lived insight.
Bottom Line
The 5 vrittis — pramana, viparyaya, vikalpa, nidra, and smriti — are Patanjali’s catalogue of every kind of mental activity. They are not obstacles to be destroyed but movements to be recognised. When you can name a vritti as it arises and notice whether it is klishta or aklishta, you have stepped into the practice that Yoga Sutra 1.2 announces: the gradual stilling of the mind that is yoga itself. Hold sutra 1.6 the way you would a field guide. With time, the categories stop being intellectual labels and become the very texture of self-observation.
