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.
I personally recommend Child Dianetics to anyone who has or deals with children. It's a total manual on how to get along with them. It's definitely worth reading one book to improve your relationship with not only your kids but with any children that you happen to run into.
