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.

Spannungsbogen

The Fremen were supreme in that quality the ancients called 'spannungsbogen' — which is the self-imposed delay between desire for a thing and the act of reaching out to grasp that thing.

— from The Wisdom of Muad'Dib by the Princess Irulan
