Mahavakayas such as Tat Tvam Asi, Aham Brahmasmi are short pithy statements of the Upanishads that declare the essential unity of the individual Self, Atman, with the Supreme Reality, Brahman. In essence they reveal that one is indeed what one is searching for – undying existence, supreme knowledge and infinite bliss. These declarations are the doorway to Truth. All the yogas mentioned in the earlier three episodes are only to prepare oneself for this ultimate Self-Knowledge.
