Life is like a piece of string with a lot of knots tied in it. The knots are the karma you're born with from all your past lives, and the object of human life is to try and undo all those knots. That's what chanting and meditation in god consciousness can do. Otherwise you simply tie another ten knots each time you try to undo one knot. That's how karma works.
The universe that we inhabit and our shared perception of it are the results of a common karma. Likewise, the places that we will experience in future rebirths will be the outcome of the karma that we share with the other beings living there. The actions of each of us, human or nonhuman, have contributed to the world in which we live. We all have a common responsibility for our world and are connected with everything in it.
