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: A New Slant on Life.
This book really helped me with solving problems that deal with human relationships. I feel closer to my family and my freinds. I have used it in my work as a teacher to build better rapport with my students and their parents, and with fellow educators.
