Dhammapada 1:5

Animosity does not eradicate animosity.
Only by loving kindness is animosity dissolved.
This law is ancient and eternal.

This is the western truth that two wrongs do not make a right. It is interesting how other cultures come up with identical truths. Only by loving kindness is animosity dissolved. This is another global truth, you get more bees with honey than vinegar. If you get in an accident with someone it does no good to point at the other person and be angry. It only escalates the situation. In my own life I see this. It is a hard thing to do when angry to not be instantly in attack mode. Maybe something wrong and hurtful will come out. This solves nothing. We only gain the advantage by remaining calm and allowing kindness to rule. When this happens we see the reduction of hostilities and the situation diffusing.

This law in ancient and eternal - however it is difficult to use daily. Maybe the world leaders should practice this one a bit more.
