Begin the morning by saying to thyself: I shall meet with the busy-body, the ungrateful, arrogant, deceitful, envious, unsocial. All these things happen to them by reason of their ignorance of what is good and evil. But I, who have seen the nature of the good, that it is beautiful, and of the bad, that it is ugly, can neither be injured by any of them, nor be angry with my kinsman.
