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 the loss of my mother. It help me handle body problems like asthma. Reading this book helped me to understand and do better in life and it helped me be able to help others.
