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 Science of Survival.
The data in this book is invaluable. A person cannot possibly flourish and prosper and have fun in today's world unless you have this information.
The book helped me with communicating better with people, and, as a result, being able to recognize who I want to be friends with and who I don't want to associate with. By learning and applying the information in this book I am able to run a busy, stress-free, chiropractic practice.
