Breath is the mystery; in it is hidden the secret of life. Breath proves the existence of the life unseen. Breath is audible, at the same time inaudible. Breath is visible and at the same time invisible.

It is a certain degree of the activity of the breath and capacity through which it is acting which makes the breath audible. This shows that there exists something of which we are conscious, the source of which no one knows, which is active every moment of the day, on the model of which the mechanism of nature and art is made.

No one can explain when it came into this mortal body, and no one can say whither it goes when it leaves this body of clay. One can only say that something living came and kept this mortal body alive and left it, proving that the same body, which was once thought to be alive, was not really alive, but itself was the life. This proves to the intellect, even to that void of faith, that there is some source whence life comes and that it returns again to the same source,

Man's true self is the part of his being which knows itself to exist, which is conscious of itself. When that self takes breath as its vehicle instead of the body, then it soars up and toward the utmost heights, toward the goal which is the source and origin of all beings.
