Meditations 10.25

He who flies from his master is a runaway; but the law is master, and he who breaks the law is a runaway. And he also who is grieved or angry or afraid, is dissatisfied because something has been or is or shall be of the things which are appointed by him who rules all things, and he is Law and assigns to every man what is fit. He then who fears or is grieved or is angry is a runaway.

Marcus Aurelius, Meditations 10.25, translated by George Long

He that flies from his master is a runaway. But the Law is our master, and he that transgresses the Law is a runaway. Now he also, that is moved by grief or wrath or fear, is fain that something should not have happened or be happening or happen in the future of what has been ordained by that which controls the whole Universe, that is by the Law laying down all that falls to a man's lot. He then is a runaway who is moved by fear, grief, or wrath.

Marcus Aurelius, Meditations 10.25, translated by C. R. Haines
