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 The Way to Happiness.
This book really helped me with life. By reading and applying the principles of this book, The Way To Happiness, I have found life is more fun and productive. After studying extensively in philosophy and the healing arts for years I can appreciate the synthesis that Mr. Hubbard has accomplished. He has brought the works of the ages to light in concise, workable, and effective ideas so that most can apply and benefit both himself and those around him.
