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 Science of Survival.
This book really helped me with understanding emotions and the characteristic behavior at different emotional levels to help others become more happy and help others get through some upset. Also the data helped me to identify and disconnect ill intentioned persons just by wathching how they act.
