That self is indeed Brahman, as well as identified with the intellect, the Manas and the vital force, with the eyes and ears, with earth, water, air and the ether, with fire, and what is other than fire, with desire and the absence of desire, with anger and the absence of anger, with righteousness and unrighteousness, with everything—identified, as is well-known, with this (what is perceived) and with that (what is inferred). As it does and acts, so it becomes; by doing good it becomes good, and by doing evil it becomes evil—it becomes virtuous through good acts and vicious through evil acts. Others, however, say, 'The self is identified with desire alone. What it desires, it resolves; what it resolves, it works out; and what it works out, it attains.'
