Self-control is mainly achieved by abstinence, which acts against the constant demands of the mind, the senses and the body. The control over each plane is won gradually by special practices of pose, posture and movement, adapted to this purpose. Every motion and action, even each organ and muscle of the body must work under the control of the will. All the powers of the body, whether in absorption or rejection, should be mastered by self-control. For both absorption and rejection control of the breath is necessary, and by the same power all things are controlled.
