The jnani seeks to realize Brahman. He discriminates, saying, ‘Not this, not this’. He discriminates saying, ‘Brahman is real and the universe illusory.’ He discriminates between the Real and the unreal. As he comes to the end of discrimination, he goes into samadhi and attains the Knowledge of Brahman.
