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 Modern Science of Mental Health.
This book really helped me with understanding other people and to really know what makes others achieve their goals or not achieve their goals. That a person's past stops their future and to realize what the puzzle is and what holds them back. And apply the exact steps as laid out in Dianetics is truly the easiest thing, you can do. The person tells you because they already know. Its just hidden from view at the moment.
