From Dune

"I must not fear.

Fear is the mind-killer.

Fear is the little-death that brings total obliteration.

I will face my fear.

I will permit it to pass over me and through me.

And when it has gone past I will turn the inner eye to see its path.

Where the fear has gone there will be nothing. Only I will remain."

"You say you're not for sale, but I believe I've the coin you'll accept. For your loyalty I offer my loyalty to you...totally."

"My son has the Atreides sincerity," Jessica thought. "He has that tremendous, almost naive honor — and what a powerful force that truly is."
