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 learning about the hidden source of upsets in life and how to get rid of them. Once you learn how to do the techniques in this book, you can free yourself and your friends on family from the effect of these upsets.
