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 being able to live a better life. It also helped me better understand myself as a spiritual being. It gave me data on professionalism, happiness, marriage, confronting difficult situations, understanding others, and the secret to greatness.
