- It is part of our nature and the experience of time to change. If nothing were changing, would you experience the passing of time? In this reality nothing can ever be created or destroyed, but its pieces can be rearranged. Once changed, can something ever change back? Or does memory prevent that? Can it only change again? Can a shape-shifter change from one form to another, then travel a loop of experience to end up back where he or she began? Is it part of your nature as a self to change? To grow? To remember? To forget? Does a goal or destination become only a port of call? A new starting place? A stop along the path you may otherwise call life?
