A key element of Bene Gesserit mental training, recited to subdue primal terror and maintain control under extreme stress. The litany reads: '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 me, I will turn to see fear's path. Where the fear has gone there will be nothing. Only I will remain.' Used as a final resort when normal calmness rituals prove insufficient, particularly against race-memory fears.
