Translated by Swami Lokeswarananda, 281 Pages, Paperback.
The Mandukya Upanisad is found in the Atharva Veda. It is one of the shortest Upanishad, having only twelve verses. It is brief, but it is self contained and very well argued presentation on non-dualism based on Gaudapada's Karika (auxiliary work). Gaudapada was the teacher of Govindapada, who was Sankara's teacher.
