Meditations 4.10

Consider that everything which happens, happens justly, and if thou observest carefully, thou wilt find it to be so. I do not say only with respect to the continuity of the series of things, but with respect to what is just, and as if it were done by one who assigns to each thing its value. Observe then as thou hast begun; and whatever thou doest, do it in conjunction with this, the being good, and in the sense in which a man is properly understood to be good. Keep to this in every action.

Marcus Aurelius, Meditations 4.10, translated by George Long

Note that all that befalls befalleth justly. Keep close watch and thou wilt find this true, I do not say, as a matter of sequence merely but as a matter of justice also, and as would be expected from One whose dispensation is based on desert. Keep close watch, then, as thou hast begun, and whatsoever thou doest, do it as only a good man should in the strictest sense of that word. In every sphere of activity safeguard this.

Marcus Aurelius, Meditations 4.10, translated by C. R. Haines
