It is most difficult for people to understand. That life has no purpose. Life has no purpose whatsoever. This is a blow to the ego. We think we're so important. We go through life having various experiences. We believe it's getting us somewhere. Yet life is totally meaningless. No purpose at all. A good example of this is the dream. When you are dreaming it appears that you have a purpose. You're doing all sorts of things in your dream. Yet you wake up and all of the things you've done in the dream. You've gone to school in the dream, you've earned a PhD, you've gotten married, you have children, you became a grandfather, grandmother. Then you awaken, it's all gone. (RA)
