Finally, let necessity, not pleasure, govern you in eating and drinking. I do not say that you must allow your body to want for nourishment. Oh, no; like any animal destined for the service of man, your body must be supported. All that is required is to control it, and never to eat solely for pleasure, We must conquer, not destroy, the flesh, says St. Bernard; we must keep it in subjection, that it may not grow proud, for it belongs to it to obey, not to govern.
--Louis de Granada,
