The Physician of souls heals by abandoning us. For He permits us to undergo some fearful suffering night and day, and then the soul returns again to its original hatred, and learns like David to say to the Lord: ‘I hate them with perfect hatred: I count them my enemies’ (Ps. 139: 22). For a man hates his enemies with perfect hatred when he sins neither in act nor in thought – which is a sign of complete dispassion.
