Mandukya Upanishad
The shortest Upanishad — only 12 verses — yet considered by Adi Shankaracharya to be sufficient alone for liberation. Explores the sacred syllable OM and the four states of consciousness: Jagrat (waking), Svapna (dreaming), Sushupti (deep sleep), and Turiya (the fourth — pure witnessing awareness beyond all states). The foundation of Advaita Vedanta. Gaudapada's Karika (commentary) is the earliest surviving Advaita treatise.
- The Mandukya Upanishad is the shortest Upanishad — only 12 verses — yet considered by Adi Shankaracharya to be "sufficient alone for liberation."
- The text explores two subjects simultaneously: the sacred syllable OM (AUM) and the four states of consciousness — showing them to be identical.
- The four quarters (Matras) of OM: A = Vaishvanara (waking state), U = Taijasa (dreaming state), M = Prajna (deep sleep), and the silence after OM = Turiya (the fourth — pure awareness).
- The Mahavakya: Ayam Atma Brahma — "This Atman is Brahman" (Mantra 2) — the most direct statement of non-duality in all the Upanishads.
- Turiya (the fourth) is not a state — it is the background awareness in which all three states appear; it is Brahman itself, pure consciousness.
- Gaudapada's Karika (215 verses) is the oldest surviving Advaita commentary — it builds on the Mandukya to establish Ajativada (the doctrine of non-origination): nothing is ever truly born or dies.
- The influence of this text on Advaita Vedanta, Buddhist Madhyamaka, and modern non-dual traditions is extraordinary.
- In the Muktika canon, this Upanishad alone is said to be sufficient for moksha.

OM — The Imperishable Syllable
Mandukya Upanishad · Chapter 1 · Verse 1
ॐ इत्येतदक्षरमिदं सर्वं तस्योपव्याख्यानम् । भूतं भवद्भविष्यदिति सर्वमोंकार एव । यच्चान्यत् त्रिकालातीतं तदप्योंकार एव ॥ १ ॥
