Besides, this breath which we breathe from morning till evening, we hardly consider what mystery is behind it. This one subject is of such great importance that if we really studied this science we would be able to understand the whole being. Yet this is the very thing of which everyone seems to be ignorant. People never think about it; they think we breathe and that is all, and they do not know how, and why. In point of fact there is something in the breath which connects the body with the soul, and the day when the breath leaves the body this connection is broken. The body remains on the earth, and the soul goes on; and therefore that which links the soul and body together must be of the greatest importance.
