`On this there is this verse: "When all desires which once entered his heart are undone, then does the mortal become immortal, then he obtains Brahman." `And as the slough of a snake lies on an ant-hill, dead and cast away, thus lies this body; but that disembodied immortal spirit (prana, life) is Brahman only, is only light.' Ganaka Vaideha said: `Sir, I give you a thousand.'
