Litany Against Fear
I must not fear.
Fear is the mindkiller.
Fear is the little death that brings total Oblivion.
I will face my fear.
I will permit my fear to pass over me and through me.
And where it has gone, I will turn the inner eye.
Nothing will be there. Only I will remain.
–in Dune by Frank Herbert
