Peace is not just the absence of war, it is not just the absence of violence, it is not just the absence of strife, it is not passivity.
Peace is the active practice of a state of mind that is at peace, that seeks peace, that acts in peace. That excludes violence both in action as in words. For that to happen, it needs peace at heart, it needs compassion, it needs humility, it needs grace.
Peace is not easy; it is the hardest thing to ever achieve and maintain. It requires strength, perseverance, and constancy. A peaceful person does not give in to negativity, does not yield to temptations of aggression, does not diminish others, even if they are wrong.
Peace can only be the goal if it is the path. That does not imply pacifism, but it means that even if you have to fight an enemy, you should do it with the goal of peace in mind. Any enemy of today will have to become a friend as soon as possible. We should never make reconciliation nor forgiveness impossible, but see them as the path out of the conflict. Every war is a war with ourselves, as we are all one. If we reject that unity, we have already lost; and once inner peace is lost, outer peace cannot be gained.
Gandhi knew that, King knew that, Thoreau knew that. Black Elk knew it, according to John Neihardt: “know the power that is peace”1.
