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 with a lot of things! It answers the REALLY BIG questions about life. The ones you've been searching for ever since you first uttered the 'WHY'. Read this book, and use the materials and you will see for yourself.
