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: The Fundamentals of Thought.
This book really helped me with increasing my understanding of myself and others. It helped my solve problems in life and improve interpersonal relationships. I have an understanding of who I really am and what I am doing. I had been looking for these answers for a long time and found them all in this wonderful book.
