My view is that our minds are incredibly powerful animals that are, during life, kept somewhat in check by the load of our bodies. Once that load is gone (or so some ancient texts teach us) the mind is like a horse off the tether. So the habits we get into here might have something to do with what happens to us afterwards. An exciting but harrowing idea, given the everyday state of my mind. But also hopeful, since that's something a person can work with.
