Does it matter why he started it? He might have had different intentions or better said a different motive, but again just like The Secret, things happen for a reason and people are going to get out of his Ideas what they need. There is a bigger picture and we are all part of that bigger picture. If he had an idea, that Idea was to bring forth a new understanding and will/did help mankind all together in their spiritual growth, even if it is/was just to define who we are not. We would not be where we are in understanding (collectively) if he never brought forth his ideas.
