As you bounce back from a deep challenge, you start anew.  There is no need to revisit it and relive it again and again.  Do you do this?  If it is to see how you can avoid such a challenge again or how you could respond more lovingly should it recur, then reliving it is beneficial.  If it is to merely rehash the lower vibrations, beware.  Start anew each moment of your existence.  The past is the past.  Drag nothing with you but lessons learned and the will to evolve.  In so doing, your challenges become gifts and not baggage.
