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 understanding how my mind worked, knowing what caused a lot of the upsets in my life, and how to get rid of that certain thing, which was preventing me from being a successful and happy person.
