There is no universe other than a dreamt universe, humanity is a part of the dream as well. Many well meaning folks want to change the world, make it a better dream, be loving and compassionate... and a large number of these folks are living miserable lives and treating the garbage collector better than their own family. They are much more concerned about appearance than the Truth. All that you need to change or improve, if that is your goal, exists right now in the totality of what you can see around you. Take care of anything you feel like taking care of, but I strongly suggest you never go outside of that approx. 25 ft radius.
The current situation in this dream is perfect when seen as a dream and very imperfect when viewed from the dreamt individual. When you can see both of these apparently mutually exclusive points of view, then decide if you want to change something or anything, or perhaps nothing at all. If you really want to contribute to this world, the best way is find out your True Nature, T/R, Enlightenment, or whatever you wish to call it.
