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 Scientology Handbook.
This book really helped me with dealing with my day-to-day life. It covers everything that someone might need to handle in everyday life situations. I can refer to this book easily and it has all the tools I need right there.
