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 Scientology: A New Slant on Life.
This book really helped me with understanding relationships, raising my children and live a much happier life. As L. Ron Hubbard says in the book: "The hardest task one can have is to continue to love his fellows despite all reasons he should not. And the true sign of sanity and greatness is to so continue".
