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: A New Slant on Life.
This book provides several essays on many different topics that have helped me in my life. Subjects like marriage, children, professionalism, the soul and many more are discussed. I think you'll find that L. Ron Hubbard's ideas on these topics are unique, insightful and very interesting.
