If you are gnawed by desire or fear you must not believe in God, who is filled with love, and who exists in you. If you believe in Him, you know that you need not wish for anything because the wishes of God always come true; and you need never be afraid of anything, because God fears nothing. The nature of a soul is so mysterious that no matter how hard we try to understand it, we will never be able to define it. —HERACLITUS
