I am Brahman, formless, of the nature of existence-consciousness-ecstasy. This is the last time this declaration appears, and its context transforms it. Chapter 20 is the culmination: here there is nothing left to say, nothing to attain, nothing to understand. The statement resonates as a final echo, not as teaching but as state. Where before there was an “I” saying “I am Brahman,” now there is only Brahman.
