Fear is the little death that brings total obliteration.
I will face my fear.
I will allow it to pass over me and through me.
And when the fear has gone past,
I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I shall remain.
To be more specific, this is the Bene Gesserit Litany against fear. If you aren't familiar with Herbert's "Dune," I won't spoil anything by explaining this fine Litany in detail. I just hope this sparks your interest enough to go out and read the book.
