The means by which life draws its power is breath. With every breath one draws in, one draws 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 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. Thought-power is necessary with both posture and breath in order to gain physical control.
