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. Dianetics is the basic manual for how to work with the mind. It is revolutionary, and it isn't like any other study of the area. Dianetic processing really works. It is a different way of looking at things -- one you won't find in any college or university today. My immersion in the materials as a Dianeticist was my first big step into Scientology. I never looked back.
