Q:Will you please post what you know on the subject of Xenu?
People say that they have recordings of L. Ron Hubbard giving a lecture on it. I don't know anything about it.
I know nothing of this apparently fictitious character, and have never heard of it, despite extensive study of Scientology. The only mention I’ve seen of this is on pretty questionable anti-Scientology websites that are clearly biased and prone to invent and embellish upon material to smear Scientology and LRH. The fact is that it appears nowhere in the extensive basic materials of Scientology. This post, by a fellow Scientologist, does a pretty good job of summing it up.
The bottom line is that this is clearly an effort to misdirect attention away from the real fundamentals of Scientology, which are sound and workable (and can be found here and here), and make it appear that the subject is some sort of UFO cult. Anyone with a little common sense can look a little further into the extensive and freely available fundamentals of Scientology and find for themselves that it is a simple, workable subject for use in improving everyday life.
