"I am just a man. But I have become what I am by accepting myself."

"Arrakis is the key to the universe. Whoever controls Arrakis controls the spice, and whoever controls the spice controls the fate of the universe."

"The real wealth of the universe lies in a person's ability to change the universe around them."

"Know that it is ignorance to think one thing; another is required to do another."

"A person is smart. People are dumb."

"He who controls the spice controls the universe."

"I must not fear. Fear is the mind-killer."
