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 Scientology: The Fundamentals of Thought.
This book really helped me with understanding the basics of life.
After years of trying to understand the reputed “wisdom” of some big name philosophers sprinkled through history, I found in this one basic book the most understandable, powerful wisdom I had ever read.
