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 The Way to Happiness.
This book really helped me. It gives me confidence that all the good things I believed in as a child are true. It's a book that very simply gives good advice on how to live happily. Every family, every person would benefit from having a copy of this 'coffee table' book.
