What is the Philosophy behind the ‘Litany Against Fear’ from the Dune Saga?

The Dune series by Frank Herbert is one of the most popular sci-fi series ever created. It has become more and more popular throughout the years. One of the most famous sayings in that series is known as the ‘Litany Against Fear’ which reads: 

"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."

On the face of it, it sounds very deep, interesting and comes across to me as very philosophical and psychological. I don’t quite grasp though its full meaning and what it is trying to communicate to the reader. I am mainly interested though in what is the philosophy behind this litany? What is its true philosophical and psychological meaning? Some people I’ve spoken to said it embodies Stoicism, Zen Buddhism, Ancient Greek Ethics etc, but I’m not sure about this. Is it good psychology or is this actually bad psychology (maybe even dangerous)? Is fear the mind-killer? Thanks.

The philosophy within the Dune universe is intended as a fusion of Zen Buddhism and Sunni Islam. However that particular quote seems more influenced by classical Stoicism or Nietzsche's views on confronting suffering.
