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 remember how messed up I was when I was 21. I read this book in 3 days. I read all day and stayed up all night and knew I found the thing that could help me. This book explained to me what was “wrong” with me and how I could fix it. A man skilled in giving Dianetics counseling came into my life shortly after I read the book and saved my life.
