In plain words
For no form would be accomplished from either of the two alone; nor is this a manifold thing. As in a chariot the felly is set upon the spokes and the spokes are set upon the hub, so these elements of being are set upon the elements of wisdom, and the elements of wisdom are set upon the breath. This breath is the self of wisdom, bliss, unaging, immortal. It does not grow greater by a good deed nor less by a bad one. For it is this that makes him do a good deed whom it would lead up out of these worlds, and it is this that makes him do a bad deed whom it would lead downward. It is the guardian of the world, it is the sovereign of the world, it is the lord of all. Let a man know, "It is my self" — let him know, "It is my self."
