“So long as a man has any regard for this corpse-like body he is impure, and suffers from his enemies as well as from birth, disease and death; but when he thinks of himself as pure, as the essence of the Good and the Immovable, he becomes free… Throw far away this limitation of a body which is inert and filthy by nature. Think of it no longer. For a thing that has been vomited (as you should vomit forth your body) can excite only disgust when it is recalled again to mind.”
