No same man could walk through the same river twice, as the man and the river have since changed.
All things come out of the one, and the one out of all things.
The awake share a common world, but the asleep turn aside into private worlds.
The seeing have the world in common.
No one can step twice into the same river, nor touch mortal substance twice in the same condition. By the speed of its change, it scatters and gathers again.
Man is most nearly himself when he achieves the seriousness of a child at play.
