I rarely post in here considering how anti sci I am, but I just wanted to chime in and say that I have read the material, including the OT levels, L rundowns, Superpower TR's (yeah, wtf) and even the base material.
The basic principles of scientology are purely based on early psychology work, which would be ironic if it wasn't so obvious. Most people could see that pretty quick but KSW keeps people too busy, too cautious and too tired to do anything but KSW.
I can admit that some of the earlier material can be useful for people that lack in certain areas. It can really Jackhammer an effective routine into someone's brain, which could help many people if applied correctly. The problem is however, that KSW itself is incorrect and damaging in the long term unless you are capable of 9000% always applying KSW to it's fullest. Of course, problems (RPF, being downstat, etc) arise when failure to do so happens, whether through fault of your own or not.
The "religious" aspect of scientology is also plagiarized from pretty much everything+bad star trek. It is used as a cloak, a shield, defense from persecution and a way to attack critics by citing religious hatred. When L.Ron himself said they were only using religion for taxes and protection that arguement loses any weight in my book.
The Idea of a spirit, or thetan or soul or whatever you want to call it isn't a unique one, every religion ever invented anywhere ever has had some view on the spirit, some stranger then others. Believing your soul is under attack by thousands (millions?) of tiny alien souls however, is just bullshit to me. People may believe what they want, but as a free human being, I have the right to believe it is full of shit, especially when it comes at a price tag of around 379,000$US at last estimate several years ago.
Now add in the front groups, the lawyers, the stories of abuse and harassment, lawsuits and threats, deceit coercion and manipulation that have been the very core of scientology as soon as it was capable and most people would have to tell themselves that something is wrong over in Sci land.
And all this is BUILT IN, it's part of KSW, and if you aren't KSW you aren't gonna have a chance of being upstat and then you may have to start paying for sec checks from bob. Bob is a friend and a nice guy, but if he doesn't discover your crime, he won't be KSW and he may get sec checked and on and on.
I could go on, one of the reasons I protest Scientology is because it is such a large and complicated organization. They spend tens of millions hiding the truth from the public, but if this is the image we get from just the information that has been leaked, the grand scope and reality of it must be all the more frightening.
All the power to you if you find something there that works, but I say that you could have found that elsewhere for cheaper (i.e free)
*Edit* Wow, that sounds harsh. Don't take it that way please =D. I have no hate on scientologists or people that it helped, I do see how the early stuff can help people but the whole thing is designed to suck them in, take their money and leave them slaves to the owners of scientology. You would need to cut out like 85% of everything scientology to get something truly beneficial to the human race out of it. I'm starting to criticize again so i'm gonna stop now.
