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 Basic Study Manual.
This book really helped me by giving me the capabilities to study/ read/ learn and apply anything I want. You should also read Dianetics: The Modern Science of Mental Health to learn all about how your mind works and Scientology: The Fundamentals of Thought to learn about how life works!
