Hekim Bey spelled correctly. An anarchist, Sufi scholar, and author of three books that are relatively easily available: T-A-Z, Immediatism, and Millennium. All have to do with direct action we can take to free ourselves, often through unmediated experience. He was a big influence on the way that Burning Man happens, and the way that it is interpreted, among other things.
A pen name for somebody else. If I told you, it wouldn't be a secret, would it?
