Change alone is unchanging.

It is hard to contend against one's heart's desire; for whatever it wishes to have it buys at the cost of soul.

A blow to the head will confuse a man's thinking, a blow to the foot has no such effect, this cannot be the result of an immaterial soul.

To me one man is worth ten thousand if he is first-rate.

The path up and down is one and the same.

The waking have one common world, but the sleeping turn aside each into a world of his own

The only thing constant is change
