Peace does not come through the agreement of egos, for it is impossible for egos to agree. Peace comes when love and mutual respect are present. When love is present, your enemy becomes like a friend who is not afraid to disagree with you. You do not cast him out of your heart just because he sees things differently than you. You listen carefully to what he has to say.
When you listen to your enemy the same way that you would listen to your friend, it is not your ego doing the listening. The Spirit inside you is listening to the Spirit inside of him.
