Sergeant Cat quoted Dune by Frank Herbert
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.
— Dune by Frank Herbert
This really reminds me of Stoicism and Buddhism. It's brilliant, and it's amazing how Frank Herbert worked so much of existing religions and philosophies into his Dune novels.
