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 Dianetics: The Modern Science of Mental Health.
This book really helped me with understanding some basics of life and how the concious and unconcious mind works. I read this book when I was young and it made sense. It can be a tough book to read, but it is worth it. The book expained to me why I acted certain ways, it explained troubles I was having in life and where they came from. Most importantly, it explained how to remove the hidden influences of the mind that boobytrapped my life.
