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 Clear Body, Clear Mind.
This book really helped me with my ability to cope with life and also with my energy levels, after doing my Purification Rundown (physical program to remove toxins from the body). With a clear mind, free from all impurities, I was able to cope better in my life.
