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 The Way to Happiness.
This book really helped me with well, let me say when I first read this book, so many every day problems ironed out for me, as it covers practical advice usable by anyone in today's somewhat confusing and hectic society. I still often refer back to it, because it has a wide range of useful information on how to get along well with others as well as how to help others achieve great happiness and productivity.
