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 gave me the information I needed to divide life into sections that were confrontable. What it takes to be really happy (It comes from you, but there is a twist). The data on marriage and children is data I use every day, It also gave me the information on how to apply the golden rule to able beings so that they are not the effect of the actions of others. This book is what I recommend to my friends who want to get info on Scientology.
