If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Dianetics: The Evolution of a Science.
kk For me this was an introduction to other Scientology books and materials. It also gave me an insight into what's known as the "reactive mind". This is something that every person needs to know about.
