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 55!
This book really helped me with the improvement of my own communication and the understanding of others that follows from communicating with them, finding and sharing their interests, and thus developing an affinity for them. With this book you truly see where people are communicating and where they are not. It also isolates what life is and what and who man really is and goes into Scientology processes that improve your control of life and communication.
