“Still round the corner there may wait
A new road or a secret gate
And though I oft have passed them by
A day will come at last when I
Shall take the hidden paths that run
West of the Moon, East of the Sun.”

“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.”
― Frank Herbert, Dune
