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: The Fundamentals of Thought.
This book really helped me by giving me a deeper understanding of the basic components of life and how Scientology can help someone live a better one and fully enjoy all of life's benefits. This book talks about the basic tenants of the Church of Scientology and how they align with the basic components of life. Read it and you'll gain a fuller understanding of how Scientology can help you fulfill your dreams and aspirations.
