Om the Eternal Witness: Secrets of the Mandukya Upanishad

The Upanishads are called shruti revelations. Madnukya Upanishad though the shortest of all Upanishads is a most revered profound Upanishad that teaches us how to know four states of consciousness: the waking dreaming and sleeping states and Turiya the fourth state beyond the first three. In this Upanishad there is a unique combination of psychology and profound philosophy; a clear exposition and understanding of four states of consciousness.
