I like this quote at the end and for me it sums up the whole of Scientology.
Mr. Kaufman concludes...
"There are of course no grades or levels except in the mind of the Scientologist; the grades and levels are simply RON's test of a pre-clear's credulities; they guide him into progressively deeper hypnotic states. What the pre-clear is run on is largely coincidental and is not what moves the needle; rather it is the thinly disguised suggestions which flow from a determined and persuasive auditor making the needle respond like a dog wagging its tail at hearing a kind word."
It must be acknowledged that Hubbard has developed a technique for doing this that warrants the study of non-Scientologists. He has in fact developed a system of biofeedback brain control based on the E-Meter.
