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 getting into Scientology. I have helped lots of people by applying the information given in this book. I recommend very strongly that every person read this book. This book will answer any question you might have had in your life and never got answered.
