Meditations 4.26

Hast thou seen those things? Look also at these. Do not disturb thyself. Make thyself all simplicity. Does any one do wrong? It is to himself that he does the wrong. Has anything happened to thee? Well; out of the universe from the beginning everything which happens has been apportioned and spun out to thee. In a word, thy life is short. Thou must turn to profit the present by the aid of reason and justice. Be sober in thy relaxation.

Marcus Aurelius, Meditations 4.26, translated by George Long

Hast thou looked on that side of the picture? Look now on this! Fret not thyself; study to be simple. Does a man do wrong? The wrong rests with him. Has something befallen thee? It is well. Everything that befalls was from the beginning destined and spun for thee as thy share out of the Whole. In a word, life is short. Make profit of the present by right reasoning and justice. In thy relaxation be sober.

Marcus Aurelius, Meditations 4.26, translated by C. R. Haines
