sparaig: > There is a reference to turiya in the mandukya > upanishad. > >From what I've read, you are correct; 'turiya' is Sanskrit for 'fourth' The Mandukhya Upanishad is the keystone in the arch of Shankara's Adwaita Vedanta.
The scripture was made famous by Gaudapadacharya, the teacher of the teacher of Shankaracharya. Gaudapada composed a famous Karika or commentary on Mundakhya and Shankaracharya composed a long commentary on both. According to my professor, this famous Upanishad is traditionally assigned to the Atharva Veda, which in turn is traditionally in the keeping of the Jyotirmath, one of the four mathas established by the Adi Shankaracharya in 812 A.D. Since the time of the first Shankaracahraya of Jyotirmath, Trotaka Saraswati, this scripture has been recited there on a daily basis at the Badrika Ashram, U.P. Himalayas. This scripture deals with the sacred syllable, the Pranava, mentioned in Yoga Sutra. It describes the three constituent phonemes which are identified with the three states of consciousness, deep sleep state, dream state, and the waking state. The famous Upanishad proposes a fourth state of consciousness which is termed 'turiya', the fourth, that is, a transcendental state, beyond the three states of wakefulness, sleeping, and dreaming. Excerpt: "Anyone who knows this is sure to construct this whole world and to become also its destruction." Purport: The fourth, on the other hand, is without constituent phonemes; beyond the reach of ordinary transaction; the cessation of the visible world; auspicious; and unique. Accordingly, the very self (atman) is Om. Anyone who knows this enters the self (atman) by himself (atman)" (288-289). Work Cited: 'Upanisads' by Patrick Olivelle (Translator) Oxford: The U.

"The clear introduction gives a comprehensive background of the Vedas. The history of Indian social structure when the Upanishads were written, their authorship, chronology, geography, etc. give the reader a comfortable feel as they go forth with their reading. The reader is also provided with a table dividing the Upanishads into the four Vedas." - review by Jasleen Matharu > > > ...we have experienced death many times.
