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 the 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.
