The Angels tell us that grievances stifle our growth. Whatever wounds we have suffered usually creates resentment or hate and anger.
Currently, different events in the world are showing us these acts of anger that are expressed in extreme forms of violence. How much hurt do these acts cause? Are they actually payment for the original act of whatever aggression? It seems that the cycle keeps escalating without anyone achieving satisfaction.
Is there a solution for this cycle? Yes, however, the solution is in each person. The individual makes the choice to act or not to act.
