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 Introduction to Scientology Ethics.
This book really helped me with handling a personal ethical situation that was really ruining my life. The book lays out the exact steps one needs to take to get honest and straight with the world and oneself. The material in this book was truly lifesaving for me.
