Man breathes, but he does not breathe tightly. As the rain fails on the ground and matures little plants and makes the soil fertile, so the breath, the essence of all energy, fails as a rain on all parts of the body. This also happens in the case of the mind, but man cannot even perceive that part of the breath that quickens the mind; only that felt in the body is perceptible, and to the average man it is not even perceptible in the body. He knows nothing of it, except what appears in the form of inhalation and exhalation through the nostrils. It is this alone which is generally meant when man speaks of breath.
