No man ever steps in the same river twice, for it's not the same river and he's not the same man.
God is day and night, winter and summer, war and peace, surfeit and hunger.

The nature of things is in the habit of concealing itself.
Because it is so unbelievable, the Truth often escapes being known.
The only thing that is constant is change.
