Marcus Aurelius
Meditations 4.7
Take away thy opinion, and then there is taken away the complaint, "I have been harmed." Take away the complaint, "I have been harmed," and the harm is taken away.
Marcus Aurelius, Meditations 4.7, translated by George Long
Efface the opinion, I am harmed, and at once the feeling of being harmed disappears; efface the feeling, and the harm disappears at once.
Marcus Aurelius, Meditations 4.7, translated by C. R. Haines
