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 Learning how to Learn.
This book really helped me with every aspect of knowledge - be it in school, work or pursuing other interests where some medium of study is necessary. This book should be available at every school and institution of higher learning. It should actually be a class that every student be required to take.
