The Varaha Upanishad asserts the non-dualistic premise that Brahman and Atman are one, and those who know this fear nothing, suffer nothing, and possess fortitude. He is I, states Vishnu. Become that, Ribhu; Thou am I verily, suggests Vishnu. Those high souled ones, who with the firm conviction that I am the Brahman, are the Jivanmukta, states verse 2.43 of the text.
