I believe all suffering is caused by ignorance. People inflict pain on others in the selfish pursuit of their happiness or satisfaction. Yet true happiness comes from a sense of inner peace and contentment, which in turn must be achieved through the cultivation of altruism, of love and compassion and elimination of ignorance, selfishness and greed.
Contemplative and bookish men must of necessity be more quarrelsome than others, because they contend not about matter of fact, nor can determine their controversies by any certain witnesses, nor judges. But as long as they go towards peace, that is Truth, it is no matter which way.
Peace is not merely the absence of visible conflict. Only a just peace based on the inherent rights and dignity of every individual can truly be lasting.
The example of America must be the example not merely of peace because it will not fight, but of peace because peace is the healing and elevating influence of the world, and strife is not. There is such a thing as a man being too proud to fight. There is such a thing as a nation being so right that it does not need to convince others by force that it is right.
He who does not attempt to make peace / When small discords arise, / Is like the bee's hive which leaks drops of honey / Soon, the whole hive collapses.
