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 Scientology: A New Slant on Life.
This book really helped me with questions I have had about different aspects of life.
The book presents ideas about living that make sense and that can be applied in life.
I found that the information in this book can be used to create a stable operating basis for anyone.
