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, Bene Gesserit Litany Against Fear
