II.iv.12.

  As a lump of salt dropped into water dissolves with (its component) water, and no one is able to pick it up, but from wheresoever one takes it, it tastes salt, even so, my dear, this great, endless infinite Reality is but Pure Intelligence. (The self) comes out (as a separate entity) from these elements, and (this separateness) is destroyed with them. After attaining (this oneness) it has no more consciousness. This is what I say, my dear. So said Yajnavalkya.

IV.iv.13.

  He who has realised and intimately known the Self that has entered this perilous and inaccessible place (the body), is the maker of the universe, for he is the maker of all, (all is) his Self, and he again is indeed the Self (of all).

IV.v.15.

  Because when there is duality, as it were, then one sees something, one smells something, one tastes something, one speaks something, one hears something, one thinks something, one touches something, one knows something. But when to the knower of Brahman everything has become the Self, then what should one see and through what, what should one smell and through what, what should one taste and through what, what should one speak and through what, what should one hear and through what, what should one think and through what, what should one touch and through what, what should one know and through what? Through what should one know that owing to which all this is known? This self is That which has been described as 'Not this, not this.' It is imperceptible, for It is never perceived; undecaying, for It never decays; unattached, for It is never attached; unfettered -- it never feels pain, and never suffers injury. Through what, O Maitreyi, should one know the Knower? So you have got the instruction, Maitreyi. This much indeed is (the means of ) immortality, my dear. Saying this Yajnavalkya left.

V.i.1.

  Om. That (Brahman) is infinite, and this (universe) is infinite. The infinite proceeds from the infinite. (Then) taking the infinitude of the infinite (universe), it remains as the infinite (Brahman) alone.

  Om is the ether - Brahman -- the eternal ether. 'The ether containing air,' says the son of Kauravyayani. It is the Veda, (so) the Brahmanas (knowers of Brahman) know; (for) through it one knows what is to be known.
