Mystics, therefore, have practiced for many, many years, and have found out different postures of sitting while doing certain breathing exercises. They have made a great science out of this. There is a warrior's posture, an artist's posture, a thinker's posture, an aristocratic posture, a lover's posture, a healer's posture: different postures in order to attain different objects. By those postures it becomes easy for man to attain these objects, for then he has arrived at the science of direction. Posture does not denote anything but direction.
