It doesn't matter whether or not you have a head, you must wear the right sort of hat

Go as far as you can. Go further than you can!

You do miracles if you concentrate your mind on one thing and one thing only.

How does the light of a star set out and plunge into black eternity in its immortal course? The star dies, but the light never dies; such also is the cry of freedom.

God is action, complete with mistakes, fumblings, persistence, agony. God is not the power that has found eternal equilibrium, but the power that is forever breaking every equilibrium, forever searching for a higher one.

The ultimate, most holy form of theory is action.

Die every day. Be reborn again every day.
