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

The Three Ordinary States of Consciousness

Every human being is intimately familiar with three states of consciousness, even if they have never reflected on them philosophically. There is waking — jagrat in Sanskrit — in which we perceive and interact with the gross physical world through the five senses and the body. There is dreaming — svapna: in which the mind creates its own world of subtle mental objects: images, narratives, feelings, and encounters that feel entirely real while the dream lasts. And there is deep dreamless sleep — sushupti: in which even the dream collapses and there appears to be nothing at all: no objects, no thoughts, no sense of self.

Each state has its own character. In waking, objects are experienced as external and shared. In dreaming, objects are self-created and private. In deep sleep, objects are entirely absent. The gross body is the vehicle of waking experience; the subtle body: mind, breath, and the senses as inner faculties: is the vehicle of dreaming; the causal body, the seed-state from which both waking and dreaming arise and into which they withdraw, is associated with deep sleep.

What changes across these three states is the content of experience: the objects that appear, the faculties through which they are known, the sense of self that is present or absent. What the Upanishadic tradition asks us to notice is what does not change: what is constant across all three states. There must be something that is present in waking, present in dreaming, and present even when there is no memory of deep sleep. Something that knows all three without itself being one of the three.

This is the thread that leads from the philosophy of the states to the recognition of turiya. The question is not merely theoretical. It points to a direct investigation: Who or what is it that passes through all three states and is never absent from them?

Turiya: The Fourth State

Turiya is a Sanskrit word meaning simply "the fourth." But unlike the other three: waking, dreaming, and deep sleep, which are genuinely states that arise and pass away: turiya is not a state in the same sense at all. It is not added to the sequence of waking, dreaming, and deep sleep as a fourth item in a list. It is the substratum in which all three arise, persist, and dissolve.

The Mandukya Upanishad, one of the shortest and most concentrated of all the Upanishads — just twelve verses: is devoted entirely to the nature of consciousness as revealed through the four states and the syllable Om. Its description of turiya is famously paradoxical: turiya is described as "not inward-knowing, not outward-knowing, not both, not a mass of consciousness, not conscious, not unconscious." It cannot be grasped, it is not to be seen, it is not to be seized, it has no distinguishing marks, it is beyond thought, it is ineffable.

Why such negative description? Because turiya is the knower, not the known. Every attempt to describe it turns it into an object — but turiya is precisely what cannot be objectified, because it is the subject underlying all experience. To say "I experienced turiya" is already to have missed it: in that statement, turiya has been turned into an object of experience, which is exactly what it is not.

The positive description is equally direct: turiya is pure awareness. It is the witnessing presence that is present in waking experience, present in dreaming experience, and present even in deep sleep — though deep sleep offers no content to witness. The witness is not affected by what it witnesses. It is neither happy in happiness nor sad in sadness. It is the unmoving background against which the entire movement of experience, through all three states, takes place.

This is why the Upanishads sometimes call it the fourth: not because it comes after the other three, but because it underlies all three. Waking, dreaming, and deep sleep take turns; turiya never takes a turn. It is always already present. The task of spiritual practice, in this framework, is not to produce turiya but to recognise it — to notice what has always been here.

The Mandukya Upanishad and the Teaching of AUM

The Mandukya Upanishad uses the sacred syllable AUM — often written Om: as the contemplative vehicle for understanding the four states. Each of the three sounds that compose Om corresponds to one of the ordinary states: A corresponds to waking (jagrat), U corresponds to dreaming (svapna), and M corresponds to deep sleep (sushupti). The silence that precedes, pervades, and follows the sound of Om corresponds to turiya.

This is not a merely symbolic assignment. The practice is to chant or listen to Om while holding the correspondence in awareness: as the A resonates, attend to the quality of waking consciousness. As U arises, attend to the dreaming quality. As M subsides, attend to the quality of deep sleep: the dissolution, the blankness. And then attend to the silence from which the sound emerged and into which it returns. That silence, which is not the absence of something but a presence underlying all sound — is a pointer to turiya.

Gaudapada, the teacher of Govindapada who was himself the teacher of Adi Shankaracharya, wrote the Mandukya Karika, an extensive commentary on the Mandukya Upanishad. In it, he developed the doctrine of ajatavada: non-origination. Nothing has ever actually been created; nothing ever actually changes; the appearance of waking, dreaming, and deep sleep as separate states is itself a kind of dream within the one awareness that alone exists. This is perhaps the most radical formulation of non-duality in the entire Indian tradition.

The practical implication of the AUM teaching is that meditation on Om, conducted with understanding of these correspondences, is not merely a relaxation technique. It is a precise vehicle for moving attention through the gross, subtle, and causal dimensions of experience, arriving finally at the awareness that underlies them all.

Turiya vs Turiyatita: The State and the Recognition

Many practitioners who engage seriously with meditation and self-inquiry begin to notice something that might be called a witness: a quality of awareness that seems to stand apart from thoughts, emotions, and perceptions, observing them without being caught by them. This is a genuine and significant discovery. It is what the tradition names turiya as a spiritual attainment or recognition.

But the tradition does not stop there. There is a further recognition that the tradition calls turiyatita — "beyond the fourth." If turiya is experienced as a fourth state distinct from the other three, it can become another object of spiritual seeking: something to achieve, to stabilise, to return to. The seeker becomes a witness-seeker, and the witness becomes the new identity. This is a subtle but significant trap.

Turiyatita is the recognition that turiya is not a fourth state alongside the other three. It is not the witness as a separate entity watching experience. It is the recognition that awareness itself is one's very nature: that there is no one separate from awareness who has awareness. The witness and the witnessed are both appearances within the single reality of consciousness. When this is recognised, the quality of turiyatita emerges: what Ramana Maharshi called sahaja samadhi — the natural state.

Sahaja means natural, innate, spontaneous. Sahaja samadhi is not a trance, not a withdrawal from ordinary life, not a state that is entered and exited. It is the recognition that one's ordinary life: the whole of waking, dreaming, and deep sleep — is already the play of pure awareness. Nothing needs to be excluded. Nothing is outside. The naturalness of the recognition is what makes it turiyatita rather than merely turiya.

Ramana Maharshi was explicit on this distinction. He said that nirvikalpa samadhi — the deep absorption state that is sometimes mistaken for the final recognition: is turiya. But sahaja samadhi, the natural state of one who has fully recognised their nature, is turiyatita. In sahaja, the yogin moves through the world, engages with life, speaks and acts, and yet the recognition of non-separation is not obscured. Waking, dreaming, and deep sleep arise in awareness; awareness does not arise in them.

How Yoga and Meditation Point to Turiya

The purpose of meditation, from the perspective of the non-dual tradition, is not to manufacture a special state. It is to create the conditions in which the recognition of turiya — of the witnessing awareness that is always already present — becomes possible. Most of what stands in the way of this recognition is not ignorance but inattention: the habitual outward movement of attention toward objects, never turning back to notice the awareness in which objects appear.

Deep meditation begins to approach the quality of turiya not by achieving something new but by releasing something habitual. As the body relaxes, as thoughts become less dense, as the ordinary narrative of the separate self quiets, what was always in the background becomes more perceptible. Researchers studying advanced meditators report reduced activity in the default mode network — the neural system associated with self-referential thinking — and a dissolution of the ordinary subject-object boundary. What meditators describe as "the gap between thoughts" or "pure awareness without content" corresponds at the experiential level to what the tradition describes as turiya.

Yoga nidra — the practice of yogic sleep: is specifically designed to make the hypnagogic threshold between waking and sleep into a place of recognition rather than mere unconsciousness. In yoga nidra, the practitioner is guided to maintain awareness while the body enters the state of sleep. The gross vehicle withdraws, the subtle vehicle relaxes, and the practitioner is positioned at the edge between the causal and the turiya. What is being cultivated is precisely the capacity to notice the awareness that persists even as the ordinary mind subsides.

Self-inquiry — the direct question "Who am I?" or "What is aware?" — takes a different approach. Rather than deepening absorption through relaxation, inquiry turns attention back on itself. It asks the mind to find the one who is doing the seeking. This reverse attention — awareness looking for its own source — naturally moves toward turiya because it moves toward the subject rather than the object, toward the knower rather than the known.

Turiya in Daily Life

One of the most common misunderstandings about turiya is that it must be sought in special circumstances: in a meditation retreat, in a peak experience, in a moment of unusual stillness. But the teaching of turiya is precisely the opposite: because turiya is the substratum of all experience, it is already present in the most ordinary moments of daily life. The question is not "how do I enter turiya?" but "what is already present in every moment of waking, dreaming, and deep sleep, regardless of their content?"

Several informal recognition practices have been used in the tradition to draw attention to this always-present awareness. The moment of waking in the morning — before thought resumes, before the mind reaches for its agenda, in the few seconds when consciousness has returned from sleep but the storyline of the day has not yet begun — is a natural glimpse of the background awareness that turiya points to. This moment is not manufactured; it occurs every morning. The practice is simply to notice it.

The gap between thoughts is another pointer. Between one thought and the next, however brief, there is a moment of pure awareness without content. This is not an absence but a presence — the awareness in which the gap appears. With practice, what seemed like a tiny hairline crack between thoughts opens into something vast: the aware space in which all thinking moves.

Falling asleep consciously — the practice that yoga nidra cultivates formally — is a third pointer. As the body falls asleep, ordinary waking consciousness withdraws. If awareness can remain present during this transition — not as thought, but as bare witnessing: the recognition arises naturally that awareness does not sleep, even when the body and mind do.

In all of these practices, the recognition is the same: there is a spacious, unmoving background of awareness in which all the content of waking, dreaming, and deep sleep appears and disappears. That background never comes and goes. It never gets tired, never gets lost, never needs to be achieved. It is what you are, prior to being any particular state.

Frequently Asked Questions

Is turiya the same as samadhi?

Turiya and samadhi are related but not identical. Samadhi — particularly nirvikalpa samadhi: is a deep meditative absorption in which ordinary subject-object experience dissolves. This is sometimes described as an experiential approach to turiya. But turiya itself, as the Mandukya Upanishad describes it, is not a state of absorption that is entered and exited. It is the ever-present awareness underlying all states, including samadhi. Turiyatita — the natural state — goes beyond even the attainment of samadhi as a meditative achievement.

Can turiya be experienced in ordinary life?

This question contains a subtle paradox: turiya is not an experience in the ordinary sense, because experiences are objects and turiya is the subject in which all objects appear. However, the recognition of turiya — the noticing of the aware background of all experience — can certainly occur in ordinary life. In fact, the tradition of sahaja samadhi specifically points to recognition that is not confined to formal practice but is alive in the midst of everyday activity. The spacious background of awareness is present in every moment; it is simply more obvious when conditions are quiet.

What is the difference between turiya and deep sleep?

Deep sleep (sushupti) is a state characterised by the absence of objects: there are no gross perceptions, no subtle dream images. In this sense it is sometimes confused with turiya, because both seem to involve a kind of stillness. But in deep sleep, there is a veil of ignorance: no awareness of the absence of objects is possible during deep sleep, only in retrospect. Turiya, by contrast, is pure awareness that is present even during deep sleep and is aware of the quality of deep sleep. Turiya never sleeps; the body and mind sleep within it.

How does turiya relate to nondual awareness?

Turiya is the classical Upanishadic formulation of what the nondual traditions point to as one's true nature: pure awareness that is not divided from what it is aware of, not bounded by the body or mind, not limited to any particular state. Nondual awareness: as described in Advaita Vedanta, Dzogchen, and contemporary nondual teachers such as Rupert Spira — is the recognition that this awareness is not a possession of the individual self but is the single reality in which all apparent individuals and objects arise. Turiya is the philosophical pointer; nondual awareness is the lived recognition it points toward.
