What Is Turiya? The Fourth State of Consciousness in Yoga Philosophy

The Mandukya Upanishad — one of the shortest and most philosophically dense of all the Upanishads — identifies four states of consciousness. The first three are familiar to everyone: waking (jagrat), dreaming (svapna), and dreamless deep sleep (sushupti). The fourth — which the Upanishad calls "Turiya," simply meaning "the fourth" — is perhaps the most significant teaching in the entire body of Vedantic literature. It is described as that which pervades and underlies all three ordinary states, that which is the ground and witness of all experience.

Understanding Turiya is not merely an academic exercise. It points directly to the recognition that lies at the heart of all nondual traditions — the recognition that one's own awareness, as it is right now, is already and always in the "fourth state," already in the ground that cannot be lost, already the consciousness that the traditions call liberation. This guide explores Turiya thoroughly: what the classical texts say, how it relates to the three ordinary states, how it is accessed and recognised in practice, and what it has to do with deep sleep, meditation, and the nature of the self.

The Three Ordinary States: Waking, Dreaming, Deep Sleep

Jagrat: The Waking State

In the waking state, consciousness is outward-directed through the five senses and the mind. We perceive an apparently external world, interact with other people and objects, think, plan, remember, and engage in the ordinary activities of daily life. The waking self — called Vishva in the Mandukya — is identified with the gross body and takes the external world to be real in a solid, independent way. Most people live primarily in this state and take it to be the totality of their existence.

Svapna: The Dreaming State

In the dreaming state, the same consciousness that was engaged with the external world in waking now creates its own world from within. The dreaming self — called Taijasa — is identified with the subtle body (mind and senses) and experiences a world that is entirely self-generated but appears no less real than the waking world within the dream itself. The dream demonstrates something philosophically important: consciousness is capable of generating an apparently external world from within itself. This is a key pointer in Vedantic metaphysics.

Sushupti: Deep Dreamless Sleep

In deep sleep, all objects — both external (waking) and internally generated (dreaming) — dissolve. There is no experience of a world, no sense of a separate self, no thoughts or perceptions. Yet upon waking, we report that we slept "well" or "deeply" or "peacefully" — suggesting that some witnessing quality persisted even through the apparent absence of experience. The deep sleep self — Prajna — is described as enjoying a kind of bliss (ananda) but in an undifferentiated, unconscious way. The "bliss of deep sleep" points toward something important — the relief from the burden of ego-identification — but because it is unconscious, it is not liberation.

Turiya: The Fourth

The Mandukya Upanishad describes Turiya not as a fourth state alongside the other three but as that which pervades and is the ground of all three. The text uses the term "Prabhavapyayau" — the source of arising and the place of dissolution — for Turiya. All three states arise from and dissolve back into Turiya, just as waves arise from and dissolve back into the ocean.

The description of Turiya in the Upanishad is characteristically via negation — it is described by what it is not rather than what it positively is, because it is prior to all the conceptual and experiential content that appears within it: "Not inwardly cognitive, not outwardly cognitive, not both-wise cognitive, not a cognition-mass, not cognitive, not non-cognitive. Unseen, unenterable, unseizable, uninferential, unthinkable, indescribable. The essence of the one Self, the cessation of development, peaceful, benign, without a second — this they call the fourth."

What this is pointing to is the pure awareness that is the witness of all three states — the "light" within which waking, dreaming, and deep sleep all appear and disappear — without itself appearing or disappearing. Turiya is not another state of experience; it is the experiencer itself, prior to all experience.

Why Turiya Is Not a State

This is one of the most important distinctions in the entire Vedantic understanding of Turiya. Because it is described as "the fourth," the natural assumption is that Turiya is another state — a special meditative state achieved through practice, located "beyond" the other three. But this is not what the text or the tradition is pointing to.

If Turiya were a state, it would have a beginning and an end, it would arise and pass like the other states, and it would be an experience. But Turiya is described as that which is present throughout all states — in waking, in dreaming, in deep sleep, and equally throughout. It is the constant background — the screen within which all states appear as temporary patterns.

This is why Ramana Maharshi consistently said that Turiya is not something to be achieved but something to be recognised. It is the very awareness that is aware of these words right now. The recognition is simply the turning of attention toward its own source — the awareness becoming aware of itself rather than continuing to be absorbed in the objects it witnesses.

Turiya and Yoga Nidra

Yoga Nidra — the guided practice of yogic sleep — is often described as an exploration of the states of consciousness described in the Mandukya Upanishad. The systematic body scan and awareness rotation in Yoga Nidra guide the practitioner through different levels of experience, progressively withdrawing identification from the gross (waking-like) levels and moving toward the subtle and causal levels, eventually reaching the threshold of the "fourth" — the witnessing awareness that remains when all content of experience is released.

This is why Yoga Nidra is sometimes described as a "practice of Turiya" — though more precisely it is a practice of approaching Turiya, a systematic guided withdrawal from the three ordinary states toward the recognition of the awareness that underlies them. The deep rest of Yoga Nidra is not unconsciousness like deep sleep; it is a conscious resting in the awareness that is the ground of all states.

Turiyatita: Beyond the Fourth

Some Vedantic texts speak of a state beyond Turiya — Turiyatita, meaning "beyond the fourth." If Turiya is the recognition of pure awareness as the ground of the three states, Turiyatita is the recognition that there is no longer any contrast between Turiya and the other states. The recognition is fully integrated: waking life, dreaming, sleeping, and the deepest meditation are all seen as appearances within the one awareness. There is no longer a "retreat" to Turiya from ordinary life; ordinary life is Turiya. This integrated recognition is what the tradition calls sahaja samadhi — "natural" or "effortless" samadhi — the final non-dual recognition in which the apparent distinction between awareness and its content dissolves.

Frequently Asked Questions

Can Turiya be experienced?

Turiya is not an experience in the ordinary sense, because all experiences are objects within awareness. Turiya is the awareness itself — the subject, not an object. It can be recognised — directly apprehended — but not "experienced" in the way that thoughts, feelings, or perceptions are experienced. The recognition is more like the screen becoming aware that it is a screen rather than becoming absorbed in yet another film.

What is the relationship between Turiya and deep sleep?

In deep sleep, all objects dissolve and only the ground of awareness remains — but it is veiled by unconsciousness. Turiya is the same ground, but recognised consciously. Yoga Nidra can be understood as a practice that explores this boundary — maintaining awareness as the ordinary objects of waking experience are gradually released, approaching the conscious recognition of the ground that deep sleep approaches unconsciously.

Is Turiya what Buddhists call "rigpa"?

The Tibetan Buddhist concept of Rigpa — "pure awareness" or "primordial awareness" — describes very similar territory to Turiya. In Tibetan Buddhist practice (particularly Dzogchen and Mahamudra), Rigpa is the direct recognition of the nature of mind — luminous, open, and beyond all conceptual elaboration. The philosophical frameworks differ (Advaita posits Turiya as an ultimately real Atman/Brahman; Tibetan Buddhism is more cautious about ontological claims) but the experiential pointing is closely related.

How do I recognise Turiya?

The most direct approach comes from Ramana Maharshi: simply turn attention back toward its source. Before the next thought arises, there is awareness. Before the sense of being a person, there is the sense of being — of presence. Rest as this simple sense of being-aware, prior to all content. This is not a technique to achieve something new; it is the recognition of what is always already the case. Turiya is not found by going somewhere else; it is found by seeing clearly what is already here.
