No same man could walk through the same river twice, as the man and the river have since changed.
All things come into being by conflict of opposites.
The only constant is change.
It is wise to listen, not to me but to the Word, and to confess that all things are one.
Nothing endures but change. There is nothing permanent except change. All is flux, nothing stays still.
The gods are immortal men, and men are mortal gods.
