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.”

The mind of the believer stagnates. It fails to grow outward into an unlimited, infinite universe.”

By your belief in granular singularities, you deny all movement—evolutionary or devolutionary. Belief fixes a granular universe and causes that universe to persist. Nothing can be allowed to change because that way your non-moving universe vanishes. But it moves of itself when you do not move. It evolves beyond you and is no longer accessible to you.
