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 really helped me with basic understandings of life! It was such a relief to read this book. It told me why things are the way they are, and gave simple solutions to make situations easier. It really does give you a new slant on life!
