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 with getting along with others and getting things accomplished.
It is a physically small book but, it has enormous information. I found that some of the simplest statements resulted in huge concepts and understanding.
