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: The Evolution of a Science.
This book really helped me with actually understanding who I was! The communication was so clean and that it clear me up! Around the time I was reading it, my life had not been going in a positive direction and I was without hope of that ever changing. However, opening this book, it just magically changed my viewpoint on life and it started going the way I wanted it to.
