The power of sex is due to the sexual division of virtually all of creation. Male and female were not created to exist separately. Woman was made to complete man; and man, woman — anatomically, biologically, emotionally, mentally and spiritually. The power of the sex drive springs from the longings of the incomplete being for completion. A divided creation consequently suffers, longing for union and fulfillment…The union sought, however, is more than sexual. It is a longing for a personal union of which the sexual is but a part and not the whole.
