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 Scientology: The Fundamentals of Thought.
This was one of the first books I read in Scientology. I found the information so logical and workable. After reading this book, my understanding of myself and life increased. It gave me information that I could apply immediately in my life and it worked. It's incredible!
