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 understanding the situations I have been in, and clear them up, even if it is ages ago that they happened, as well as clearing them up. It still helps me in all areas of my life, and I can help others to get the same understanding and success as I have.
