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 coming to terms with the death of my father. I was unable to confront or talk about my father after his death. I then went on to receive some of the processes that are mentioned in the book(auditing) and was free of this inhibition and much, much happier as a result.
