The means by which life draws its power is the breath. With every breath one draws in, one draws the life and power and intelligence from the unseen and unknown life. And when one knows the secret of posture, and draws from the unseen world the energy and power and inspiration, one gets the power of sustaining one's thought, one's word, one's experience, one's pleasure, one's joy. When one asks what is the cause of every tragedy in life, the answer is: limitation. All miseries come from this one thing, limitation. Therefore the mystics have tried by exercises, by practices, and by studies to overcome limitation as much as possible. There is no worse enemy of man than helplessness. When a person feels that he is helpless, this is the end of his joy and happiness.
