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 teaches the basics on communication and also about a very important facet and basic in Scientology, the ARC Triangle (Afinity-Reality-Communication). Read this book to find out what this is and how it can help you in your life. It has helped me!
