Four attributes of Brahman: infinite (ananta), ageless (ajara), pure (śuddha), and singular (eka). There is nothing beyond this. One who knows this is freed from all fear (bhaya) — because fear always involves an “other” that threatens, and in the non-dual vision there is no other. This verse compresses the entire Upaniṣadic teaching into a single declaration: Brahman is all there is, and it is free from every limitation that the mind projects onto it.
