Marcus Aurelius
Meditations 5.2
How easy it is to repel and to wipe away every impression which is troublesome or unsuitable, and immediately to be in all tranquillity.
Marcus Aurelius, Meditations 5.2, translated by George Long
How easy a thing it is to put away and blot out every impression that is disturbing or alien, and to be at once in perfect peace.
Marcus Aurelius, Meditations 5.2, translated by C. R. Haines
