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 0-8.
This book really helped me with understanding the basics of life. I was able to align the scales listed in the book and understand the different levels of awareness a person can be in at any given time. I was able to gauge how others would react depending on their emotional tone, and help them and myself to raise their ability to handle things in life.
