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 what man is doing and why. Because human interaction is the basis of life on Earth, the absence of the data in this book was a liability for me. Knowing how the influences of others can affect me allows me to be the effect of those influences or be at cause over them according to my own desire.
