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 Child Dianetics.
This book really helped me with living with kids without going insane. It's such a fresh and new point of view about kids.
Another book I recommend is Introduction to Scientology Ethics. It has been a great help for me in running my business successfully. The ”Conditions” contained therein are invaluable.
