All is flux, nothing is stationary.

If one does not expect the unexpected, one will not find it out, since it is not to be searched out, and difficut to compass.

Unless you expect the unexpected you will never find it, for it is hard to discover and hard to attain.

There is nothing permanent except change. Nothing is permanent except change. The only constant is change. Change is the only constant. Change alone is unchanging.

He who hears not me but the logos will say: All is one.

The unlike is joined together, and from differences results the most beautiful harmony.

Man, like a light in the night, is kindled and put out.
