The breath in its different aspects acts differently; in every direction the breath does a special work. The breath has a special work with every organ of the body, and it has its particular influence upon every element of which the physical body consists. Every movement that one makes is directed by the power of the breath; at the same time, the breath alone has the power to stop any motion. For instance, walking, running, sitting and standing are actions done by the power of the breath; and trembling, shivering, or waving the hands or feet without control show lack of power in the breath.
