Why Resentments!

If any differences or disappointment took place then
Yes..It's time to settle those differences and look forward to the future for divine work.. in reality everything is divine as long as we not in duality..
Resentment has been described as a mixture of disappointment, anger, and fear. We don't realize it that if we hold on to resentment, we are still living in the past, which no longer serving us.. only the lessons learned..thats all.... 
Or Once the energy shifted then no more looking back...
