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 Dianetics 55!
This book really changed my life by giving me the formula for succesful communbication, which prior to Scientology was unknown. The basics on communication contained in the text are applicable to all aspects of life and personal relationships.
