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.
This book truly gives one the science to survive in our sometimes trying and confusing world. It gives invaluable information on how to determine who can be trusted and how to tell who your good friends and colleagues are and should be and how to make right judgement calls.
