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 solutions to problems that I had met all along a lifetime. I had great pleasure through the reading of this book. Each chapter changed my viewpoint fot the better. It is easy to read, short and confortable to carry around.
