Everything flows and nothing abides. Everything gives way and nothing stays fixed.

No man ever steps in the same river twice, for it's not the same river and he's not the same man.

Those who love wisdom must investigate many things

It is weariness to keep toiling at the same things so that one becomes ruled by them.

The opposite is beneficial; from things that differ comes the fairest attunement; all things are born through strife.

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.

God is day and night, winter and summer, war and peace, surfeit and hunger.
