Frank Herbert. Dune (№ 22280)

Fear is the mind killer. Fear is the small death that brings oblivion. I face my fear, I will let it pass through me. And when he comes through me, I turn around and look at the trail of fear. Where the fear has passed, there is nothing left.
Where the fear has passed, only I will remain.
(Fear is the mind killer. Fear is a small death, entailing the complete destruction. But I'll meet your fear and accept it. I'll let it pass over me and through me. And when he passes through me, I will turn my inner eye to its path; and where there was fear, there will be nothing - only I, myself.)
