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 Self Analysis.
This book really helped me with seeing my stengths and weaknesses. It helped me break things down into component parts so I could analyze myself and others. More importantly, a technology was prescribed that armed me with the tools and enabled me to handle my weaknesses and to enhance my strengths.
