The past is a trail you leave behind, much like the wake of a speedboat. That is, it's a vanishing trail temporarily showing you where you were. The wake of a boat doesn't affect it's course-obviously it can't since it appears behind the boat. So consider this image when you exclaim that your past is the reason you aren't moving forward.
Wayne DyerThe soul is the birthless, deathless, changeless part of us - the part of us that looks out from behind our eyes and has no form.
