Heretics of Dune (Dune, #5)

by Frank Herbert

“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 do not listen to your soul, but listen instead to your anger and your rage.”
