So you are saying that there was a large positive aspect about your involvement with Scientology? That you don't wholly regret becoming a member?
I don't know if I'd put it that way. I think I was one of the lucky ones. I spent relatively little money on it, never joined the Sea Org, and left after 7 years instead of 20 or 30. I was only 30 years old when I left and I hadn't burned all my bridges behind me, so the transition back to the "wog" world wasn't too difficult.
There is
some good in scn, mostly in the beginning. You have a big win in the beginning, so you want more, but as you go on there's less and less. After a while you're just hypnotizing yourself into believing you're still having wins. In scn you are always rehearsing your wins and applauding (literally) other people's wins.
The best thing in scn is the Comm Course, usually the first course people do. Unfortunately I can't even recommend that, because the scios will immediately be after you to do more, and they can be VERY convincing. They also lie like mad and never bat an eye, because they believe -- truly believe -- that YOU MUST DO SCN. YOU MUST GO UP THE BRIDGE. And they will do and say whatever they think is necessary to get you to do that.
You also realize, after you've been in scn for a while, that the ultimate goal of scn is TO TAKE OVER THE WORLD. Yes, as crazy as that sounds, it's true. Fortunately, I don't think they have much of a chance of doing so.
I strongly advise you not to have anything to do with scn. If you think you need therapy, there's other, much better therapy. If you're looking for enlightenment, there are lots of other GENUINE spiritual practices that aren't there just to take your money. I would suggest you look into those.
