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 realizing that there was a way to be happy. I discovered there is a technology that exists that can help me to handle life. I realized I had been my own worst enemy and that I could turn myself around and make my own life just as I wanted it to be with he help of Mr. Hubbard and his technology.
