This is true not only for individuals but for groups, societies, and species. Only through motion do we advance, and motion will create continuous situations of dis-equilibrium and the subsequent adjustments. As we become experienced in this, we expand the levels and ways in which we can adjust. We become better at regaining equilibrium, and thus can achieve it more regularly. I have made a few key statements about the nature of balance.
Balance exists in motion.
Once you achieve balance, you will always know how to regain it. Even when you regain balance, things change. Balance exists in relaxation and acceptance. Balance is our natural state. Balance is everything.
