The most common approach is still through a "personality test" once completed, the scientologist will tell the person that the test pinpointed some things that are keeping the person from success andbhappiness and that these things can be fixed through "auditing" which is basically a bogus onebon one counseling session, ranging in price from $40 to $500 each. Sadly, the auditing never ends and since it does nothing hut restructure the persons thinking to believe that scientology is great and is in fact fixing their problems, some people report becoming in debt to the tune of hundreds of thousands of dollars.
It is a very dangerous and very aggresive cult. And it started not as a religion, but as dianetics, a model of mental health and counseling rejected by the APA and AMA as having no value or scientific merit.
But, as a religion in America, Hubbard was able to circumvent laws and sell this high priced quackery which always does more harm than good.
Example? I have never met an "enlightened" scientologist, and for that matter, never met a mentally healthy one either.
