Whoever doesn't know the truth of himself, suffers uselessly for the sake of ignorance. Whoever works to know the truth of Self, agrees to suffer ignorance for the sake of Wisdom. Becoming wise, he "slays" the lower self, as well as its suffering. And in having transcended the useless suffering born of self-ignorance -- and the death it leads to -- he shares in the birth and burden of creation, in which can be found no greater peace or joy.
