Day by day, what you do is who you become.

Of all whose words I have heard, no one attains to this, to know that wisdom is apart from all.

All is flux, nothing is stationary.

The awake share a common world, but the asleep turn aside into private worlds.

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.

Presumption must be quenched even more than a fire.

You cannot step twice into the same river.
