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 Dianetics: The Modern Science of Mental Health.
This book really helped me with my goal in life which has always been to help others. Before I read this book I put a great deal of effort into helping others but found that material help had minimal benefit. After reading the book, I trained as a Dianetics Counseller. Since then, I have been able to help hundreds of people to help themselves to more confidence, ability and happiness.
