Fear is nothing but illusion which is blocking the view of human mind
Fear is the worst prison, only you can lock yourself and free yourself
Fear keeps your mind clouded and demoralize your being
Fear can fetter your body, mind, soul and spirit
Shine your light! and face your darkest fear
Look directly at your fear in the eyes
It will be daunted by your courage
You will be free forever.
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.
— Frank Herbert, Dune 1965.
