Philoxenus of Mabbug

Remember Lot's wife, who, because the love of her kinsfolk and the outcries of her beloved ones constrained her, turned and looked back behind her, and became a pillar of salt, even as is written concerning her; and because her soul had not been salted with the fear of the Highest she became a destructible salted thing. Remember then this woman who was in doubt, and who perished, and be thou not in doubt like unto her, and turn not thyself backwards, lest thou remain in the place where thou art. For the soul that turneth and looketh backward after it hath gone forth on the journey in this path becometh a senseless pillar, and as the wife of Lot ceased from bodily feeling, and thereby became a pillar of salt, even so also here the mind, which looketh behind it always at corruptible things, ceaseth to feel, and becometh stupefied at spiritual things; because the remembrance of the world maketh us to possess dulness of heart, and it defileth the purity and innocency of the soul.
