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 an understanding about how people are living.
It was an answer to why things happen and why can somebody do something and another one cannot...
What are the biggest problems in people's lives and how can one handle these.
If you read this book you won't be the same person again - you will understand more.
