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 has helped me understand others better. Until I read the book I didn't understand why other people acted in certain ways that were disturbing and why I would do things that would later regret.
After I read the book I understood others better and I was also able to help others as well, not to mention that I would now act much better toward others, everyone benefited.
