Man is most nearly himself when he achieves the seriousness of a child at play.
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.
Change alone is unchanging.
Opposition brings concord. Out of discord comes the fairest harmony.
When men dream, each has his own world. When they are awake, they have a common world.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day.
