The Enchiridion (11-15)

Never say of anything, I have lost it; but, I have restored it. Has your child died? It is restored. Has your wife died? She is restored. Has your estate been taken away? That likewise is restored. But it was a bad man who took it. What is it to you by whose hands he who gave it has demanded it again? While he permits you to possess it, hold it as something not your own; as do travellers at an inn.

If you would improve, lay aside such reasonings as these: If I neglect my affairs, I shall not have a maintenance; if I do not punish my servant, he will be good for nothing. For it were better to die of hunger, exempt from grief and fear, than to live in affluence with perturbation; and it is better that your servant should be bad than you unhappy.

Begin therefore with little things. Is a little oil spilt or a little wine stolen? Say to yourself, This is the price paid for peace and tranquillity; and nothing is to be had for nothing. And when you call your servant, consider that it is possible he may not come at your call; or, if he does, that he may not do what you wish. But it is not at all desirable for him, and very undesirable for you, that it should be in his power to cause you any disturbance.

If you would improve, be content to be thought foolish and dull with regard to externals. Do not desire to be thought to know anything; and though you should appear to others to be somebody, distrust yourself. For be assured, it is not easy at once to keep your will in harmony with nature, and to secure externals; but while you are absorbed in the one, you must of necessity neglect the other.

If you wish your children and your wife and your friends to live forever, you are foolish; for you wish things to be in your power which are not so; and what belongs to others to be your own. So likewise, if you wish your servant to be without fault, you are foolish; for you wish vice not to be vice, but something else. But if you wish not to be disappointed in your desires, that is in your own power. Exercise,

Remember that you must behave as at a banquet. Is anything brought round to you? Put out your hand, and take a moderate share. Does it pass by you? Do not stop it. Is it not yet come? Do not yearn in desire towards it, but wait till it reaches you. So with regard to children, wife, office, riches; and you will some time or other be worthy to feast with the gods. And if you do not so much as take the things which are set before you, but are able even to forego them, then you will not only be worthy to feast with the gods, but to rule with them also. For, by thus doing, Diogenes and Heraclitus, and others like them, deservedly became divine, and were so recognized.
