The reason Scientologists accept Hubbard’s bizarre story about Xenu is that by the time they reach OT 3, they have been “remembering” their own outlandish space opera “whole track” stories during auditing, perhaps for several years.
Why question Hubbard’s tale about mass alien genocide 75 million years ago, when you’ve been
“seeing” yourself as some kind of Buck Rogers fighting enemies and bedding beauties from one end of the galaxy to the other?
