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 getting started in life. This was the starting point for me as a Scientologist. When reading the book I was so happy that someone had found the answers and was sharing them to help others find the truth about life.
