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 Modern Science of Mental Health.
This book really helped me with answers. I read one half of Dianetics during a Christmas break and the other half on year later. It is still my favorite book from which I got hope that I could find answers to the questions I had and the ones I will have.
