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 Problems of Work.
This book really helped me with learning about what confusion was. Before this book I was confused many times but did not have a clue of what was going on but early in this book I learnt about CONFUSION not only what is was but also how to handle it! So your first step in handling confusion is to bye that book then read and then uses the material from the book
