Give up Ahamta-Mamata, I-ness and Mine-ness. Behold the Atman in all, behold thy Self as the All. Behold thy Self as the world. This is Jnana or wisdom. For a Vedantin samadhi has no value. It is the opposite state of Vikshepa(The tossing of the mind which obstructs concentration). He wants only Jnana. He praises only Jnana, the wisdom of the Absolute. Which is beyond Vikshepa and Samadhi, Satyam Jnanam Anantam Brahman.
