The Mandukya Upanishad is the shortest of the principal Upanishads, containing only twelve prose verses. It is embedded in the Atharvaveda and is conventionally dated between the 5th century BCE and the 2nd century CE. The text’s central focus is the syllable AUM and the four states of consciousness it represents. The Karika commentary on this text by Gaudapada (c. 7th century CE) was the principal basis for Adi Shankara’s Advaita Vedanta. This article unpacks the twelve verses.
What the Upanishad teaches in twelve verses
The text opens with the assertion that AUM is everything: past, present, future, and what lies beyond time. It then sets up an equation: AUM as four-fold sound (the three letters A, U, M plus the silent fourth) corresponds to Atman as four-fold consciousness. Each verse expounds one of the correspondences. The whole text is about three pages in standard Sanskrit print. Despite its length, the Mandukya is considered the most concentrated Upanishadic statement of non-duality.
The four states of consciousness
- Jagrat (waking, A): Vaishvanara, the cosmic person, awareness directed outward to the gross world through the seven openings of the body and the nineteen instruments of perception and action.
- Svapna (dream, U): Taijasa, the “luminous one,” awareness directed inward to the subtle world of mental impressions, without external sensory input.
- Sushupti (deep sleep, M): Prajna, the “knower,” unified consciousness with no distinction of subject and object, described as “a mass of consciousness” (prajñāna-ghana).
- Turiya (the fourth, the silence after AUM): the unqualified Atman, neither inward nor outward, neither dual nor non-dual, the ground that underlies and transcends the other three.
The text’s structural elegance lies in how the three audible sounds (A, U, M) correspond exactly to the three commonly experienced states (waking, dream, deep sleep), while the fourth (Turiya) corresponds to the silence after the chant. Turiya is not a fourth state in the same sense as the other three; it is the witnessing awareness that is present through all of them.
The mahavakya: “ayam atma brahma”
The second verse of the Mandukya contains the mahavakya ayam ātmā brahma: “This Atman is Brahman.” This is the fourth of the four Vedantic great statements (the others being aham brahmasmi, tat tvam asi, and prajnanam brahma). The mahavakya states the identity in the most concise form possible: the Atman that is the witness of waking, dreaming and deep sleep is identical with Brahman, the absolute ground of being.
The Gaudapada Karika and its expansion
Gaudapada’s Mandukya Karika, a commentary in four chapters and 215 verses, is the founding document of Advaita Vedanta. The Karika is so authoritative that the Mandukya Upanishad is rarely read without it. Gaudapada develops the Mandukya’s four-state model into the doctrine of ajatavada (non-origination), the position that the world has never actually come into being; it is an appearance, like dream content, projected by the witnessing Atman. Adi Shankara wrote his commentary on the Mandukya and the Karika together; the result is the foundational text of mainstream Advaita.
How AUM is parsed in the text
The Sanskrit syllable AUM (also written OM) is treated by the Mandukya as a tri-partite vibration:
- A: the open sound from the back of the throat, corresponding to waking, to the cosmic body, to creation.
- U: the rolling sound through the mouth, corresponding to dreaming, to the subtle body, to preservation.
- M: the closed sound at the lips, corresponding to deep sleep, to the causal body, to dissolution.
- The silence after: the unchanging, the witness, Turiya.
The full meditation prescribed by the Mandukya tradition is to chant AUM, pay attention to the way each sound proceeds and merges into the next, and then attend to the silence at the end. The silence is treated as the gateway to Turiya. The practice is described in the Karika as amatra meditation: meditation on the “measureless” fourth.
For what it’s worth, the Mandukya is the Upanishad that benefits most from being read alongside the Karika. On its own, the twelve verses can read as cryptic; with Gaudapada’s expansion, the framework opens up into a complete philosophical position. For someone reading the Upanishads in sequence, the conventional order is Isha, Kena, Katha, Prashna, Mundaka, Mandukya, with the Mandukya treated as the synthesis. The text’s brevity is deliberate; it assumes the reader has covered the longer Upanishads first.
Where the text fits in the Atharvaveda
The Mandukya is one of the three principal Atharvaveda Upanishads, alongside the Mundaka and the Prashna. All three are short by Upanishadic standards. The Atharvaveda itself is the latest of the four Vedas, dated to roughly 1200-900 BCE; the Mandukya is from a much later stratum, composed in the late Vedic to early post-Vedic period. Its position in the Atharvavedic canon is conventional rather than necessitated by content; the Mandukya’s themes are not specifically Atharvavedic in flavour.
Common questions
Why is the Mandukya considered the most important Upanishad?
The Muktika Upanishad, which lists the canonical 108 Upanishads, says that if a person cannot read all of them, the Mandukya alone is sufficient for liberation. The reason is its compactness: it states the identity of Atman and Brahman through the AUM-Turiya equation in twelve verses. Adi Shankara and the Advaita tradition treat it as the most condensed statement of non-duality. Its short length and its centrality to Vedanta are linked.
Is Turiya a state someone can experience?
The Mandukya and Gaudapada are careful here. Turiya is not “another state” in the sense of waking, dream and deep sleep. It is the witnessing awareness that is present in and through all three. To “experience” Turiya is not to enter a new state but to recognise the unchanging witness that has been present all along. In practical meditation, the access is described as resting attention in the awareness that knows the comings and goings of the other three states.
Does the Mandukya describe a fifth state?
The Mandukya itself stops at four. Some later texts and modern teachers describe a “fifth state” called Turiyatita, “beyond the fourth”, but this is not in the Mandukya. The Karika maintains the four-state structure throughout. The classification of more advanced states (savikalpa samadhi, nirvikalpa samadhi, sahaja samadhi) comes from the Yoga Sutras and later Yoga-Vedanta literature, not from the Mandukya itself.
One limitation worth noting
Modern popular writing on the Mandukya often presents the four-state model as a neurological claim (waking and dream sleep have empirical correlates in EEG; deep sleep is well-studied; Turiya could be identified with certain meditative states). The Upanishad is making a metaphysical and contemplative claim, not a neurological one. The four-state model and the brain-state literature can be compared but should not be conflated. The text’s authority rests on contemplative practice, not on neurophysiology.
