The would-be-illumined person must conform to the double action of nature in him: to the outgoing and incoming breaths. So his illumination, when it happens, must be there and here: in the mind and in the body. The two together form the equilibrium of the double life we are called upon to live: that is, being in the world and yet not being of it. In the prolongation of the expiring breath we not only get rid of negative thought but also of the worldliness, the materialism, of keeping to the physical interests alone. With the incoming breath we draw positive, inspiring remembrance of the divine hidden in the Void. Hence we are there in the mind and here in the body. We recognize the truth of eternity, the act in time. We see the reality of the Void, yet know that the entire Universe comes forth from it.
