Time is like a river made up of the events which happen, and a violent stream; for as soon as a thing has been seen, it is carried away, and another comes in its place.
Reflecting on impermanence, Marcus likened time to a river. He encouraged Romans to live presently, understanding that clinging to any moment is as futile as holding back a stream.
Everything flows. Live fully, but let go freely.
"No man ever steps in the same river twice."
