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 Introduction to Scientology Ethics.
This book really helped me with straightening out my life and then giving me a straight path to follow. I found this book very interesting and very useful, every piece of information in it applies to everyday life. You should also read Dianetics: The Modern Science of Mental Health, to find out how the mind really works, it's fascinating.
