Litany against fear
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.
[The litany against fear is an incantation used by the Bene Gesserit throughout the series to focus their minds and calm themselves in times of peril.]
