Turiya

Turiya (तुरीय) — “the fourth” — is the Upanishadic name for pure consciousness beyond the three states of waking (jagrat), dream (svapna), and deep sleep (sushupti): not a fourth state alongside the others but the witness-light common to all three.

Overview

The Mandukya Upanishad’s twelve verses map the states to the syllable AUM — A waking, U dreaming, M deep sleep, the silence after the syllable the fourth — “not inwardly cognitive, not outwardly cognitive… unseen, incapable of being spoken of, the self, to be realized.” Gaudapada’s Karika made turiya the ground of his ajata (no-creation) doctrine; Kashmir Shaivism grades it — turiya as the fourth, turiyatita (“beyond the fourth”) as the fully unfolded state — reading even the cosmos as the fourth’s vibration. Ramana and modern Advaita made the term the standard for the ever-witnessed awareness.

Significance

Turiya is Indian consciousness-studies’ most precise contribution: the observation that what remains constant across the three states is the referent of “I” — the fourth — and that all experience presupposes it.
