After enjoying himself and roaming in the dream state, and merely seeing (the results of) good and evil, he comes back in the inverse order to his former condition, the waking state. He is untouched by whatever he sees in that state, for this infinite being is unattached. 'It is just so, Yājñavalkya. I give you a thousand (cows), sir. Please instruct me further about liberation itself.'
