"'A man who gives way to his passions and suffers for it is like a man who is shot at by an enemy, catches the arrow in his hands, and then plunges it into his own heart. A man who is resisting his passions is like a man who is shot at by an enemy, and although the arrow hits him, it does not seriously wound him because he is wearing a breastplate. But the man who is uprooting his passions is like a man who is shot at by an enemy, but who strikes the arrow and shatters it or turns it back into his enemy’s heart. As the psalmist says, ‘Their own sword shall enter their own heart and their bow shall be broken to pieces.’'"
