When you see life’s pleasures, beware that they might not distract you, for they conceal death’s snares. Likewise a fisherman casts not his hook to no purpose. As bait for his hook, the enemy uses the delusion of sensuality to arouse desire, that he might thereby catch men’s souls and subject them to himself. A soul which has been caught to serve the enemy’s will then serves as a snare for other souls, for it conceals the grief of sin with its apparent delight.

St. Ephraim the Syrian
A Spiritual Psalter, Psalm 43
