Tomorrow I am going to the dentist, and in all probability will need a root canal. One thing that has been helpful to me in the past in facing the medium-sized fear appropriate to the dentist’s chair is the Bene Gesserit litany against fear, from Frank Herbert’s Science Fiction blockbuster Dune. Here it is:
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.
