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 Introduction to Scientology Ethics.
This book really helped me with In the way L. Ron Hubbard has laid out the road many books give me a lot. But the Ethics book gave me answers to many questions. Like the relationship between me and my family. The relationship with my collogues or my neighbors where I live. And people in other countries. I cannot see the change in me, but I experience a enormous change between me and others that is very positive.
