The 48 minute recording, in Hubbard's own distinctive voice, expounds Scientology's alien creation myth, whereby the earth is populated by the evil "Galactic overlord" "Xenu" (or "Xemu") and human beings are parasitized by alien spirits called "body thetans".
Scientology reportedly exposes the alien basis to its beliefs to only 10% of its followers. As recently as 2008 Scientology spokesperson Tommy Davis denied the connection on CNN.
The recording plainly shows Hubbard to have a disturbed personality, not only merely by the content of his speech, but by his manner.
Scientology threatened Wikileaks with legal action over its release over similar handwitten notes by Hubbard, citing the material as "unpublished, copyright".
Wikileaks believes the recording, given its clear authenticity, must be seen as the final nail in the coffin of Scientology's long attempts to pass itself off as something other than what it is -- a militaristic alien mind control cult that exploits the innocent with endless scams and manipulations of international corporate, banking and tax law.
