get war out of their system

I am reading newspapers, I know what is going on! But my reaction is not like yours. You are looking for a cure, while I am concerned with prevention. As long as there are causes, there must also be results. As long as people are bent on dividing and separating, as long as they are selfish and aggressive, such things will happen. If you want peace and harmony in the world, you must have peace and harmony in your hearts and minds. Such change cannot be imposed; it must come from within. Those who abhor war must get war out of their system. Without peaceful people how can you have peace in the world? As long as people are as they are, the world must be as it is.
