Marcus Aurelius
Meditations 6.4
All existing things soon change, and they will either be reduced to vapor, if indeed all substance is one, or they will be dispersed.
Marcus Aurelius, Meditations 6.4, translated by George Long
All objective things will anon be changed and either etherialized into the Universal Substance, if that indeed be one, or dispersed abroad.
Marcus Aurelius, Meditations 6.4, translated by C. R. Haines
