Marcus Aurelius
Meditations 9.19
All things are changing: and thou thyself art in continuous mutation and in a manner in continuous destruction, and the whole universe too.
Marcus Aurelius, Meditations 9.19, translated by George Long
Change is the universal experience. Thou art thyself undergoing a perpetual transformation and, in some sort, decay: aye and the whole Universe as well.
Marcus Aurelius, Meditations 9.19, translated by C. R. Haines
