Enchiridion (with a Selection from the Discourses)

But you are unwilling to endure, and are discontented; and if you are alone, you call it solitude; and if you are with men, you call them knaves and robbers; and you find fault with your own parents and children, and brothers and neighbors. But you ought when you are alone to call this condition by the name of tranquillity and freedom, and to think yourself like to the gods; and when you are with many, you ought not to call it crowd, nor trouble, nor uneasiness, but festival and assembly, and so accept all contentedly.

What then is the punishment of those who do not accept [it all contentedly] ? It is to be what they are. Is any person dissatisfied with being alone? Let him be alone. Is a man dissatisfied with his parents? Let him be a bad son, and lament. Is he dissatisfied with his children? Let him be a bad father. Cast him into prison. What prison? Where he is already, for he is there against his will; and where a man is against his will, there he is in prison.

Lately I had an iron lamp placed by the side of my household gods; hearing a noise at the door, I ran down, and found that the lamp had been carried off. I reflected that he who had taken the lamp had done nothing strange. What then? Tomorrow, I said, you will find an earthen lamp; for a man only loses that which he has. “I have lost my garment.” The reason is that you had a garment. “I have a pain in my head.” Have you any pain in your horns? Why then are you troubled? For we only lose those things, we only have pains about those things, which we possess.
