A stoic quote by Marcus Aurelius from Meditations, XII.32
How small a part of the boundless and unfathomable time is assigned to every man! For it is very soon swallowed up in the eternal. And how small a part of the whole substance! And how small a part of the universal soul! And on what a small clod of the whole earth you creep!
― Marcus Aurelius Meditations, XII.32
