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 finding the reason for man's travail. It opened my eyes and I saw for the first time what was wrong with man and saw that there is a way to handle his problems.
