Every action a person performs is either an expression of love or a call for love. When people are kind, caring and compassionate, they are expressing love. When they are cruel, hurtful or mean, they are calling for love. Their mean actions are essentially saying, "I need love."
Hurt people hurt people. Anyone who hurts other people has a gaping hole in their soul. They are feeling broken, lost and powerless. Pain is causing them to act that way.
Understanding this will help you maintain your inner peace and know how to react when a call for love comes your way.
