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 by confirming some of the things I had always believed. But even more it had helped me expand my thinking and enabled me to see ways to achieve my goals, take charge of my future and lead a happier, more productive life.
