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 putting ethics in with myself, with my family and in my work. I understood how to handle my job and how to improve my work. Using the tools in this book is the only way to improve yourself in your life and job. I also found out why oneself and other people fall out of communication with each other. This was incredible.
