Chastity makes incorporeal nature its own. Chastity is the beloved abode of Christ, and the earthly heaven of the heart. Chastity is a supernatural renunciation of nature. It is the condition in which a mortal and corruptible body competes in a marvellous way with the incorporeal. A chaste person is one who drives out love with love, and puts out the fire of the flesh with spiritual fire.

John Climacus.
