Acharya Prashant discusses the sixteenth verse of the eighteenth chapter of the Ashtavakra Gita, focusing on the nature of thought and the self. He explains that while a person who perceives duality might contemplate 'I am Brahman,' one who has transcended all perception of the 'other' has nothing left to contemplate. He describes the levels of thought, noting that at the lowest level, one identifies as a brother or father, while at the highest level, one identifies as Brahman or the void. However, Ashtavakra suggests that even the declaration 'I am Brahman' implies a remaining sense of 'I' and a boundary. Acharya Prashant emphasizes that to say 'I am' anything requires the existence of something else for comparison; if only one element existed, language and meaning would vanish. Therefore, in the state of ultimate liberation where only one essence is perceived everywhere, inside and out, even the supreme Upanishadic declaration becomes impossible because there is no 'other' left to define it.
