an analysis and comparison between the Mandukya Upanishad and the Bhagavad Gita, specifically claiming that the Upanishad acts as an explanation for a key verse in the Gita. Central to the discussion is the concept of reality as permanent and unchanging, contrasting it with the apparent changes observed in the world, which are described as merely imagined. The text explores the nature of Atman (the Self) and Brahman (Ultimate Reality), noting that Brahman includes both reality and illusion, and must be realized in the waking state amidst all present objects. Furthermore, the explanation addresses the philosophical position of Gaudapada, who ultimately rejects the assertion of even Atmanic existence, demanding silence on the matter. Finally, the source emphasizes that achieving knowledge of the universal self requires not only control of the mind but also the ability to distinguish between the true and the false.
