If there is wisdom in sacred teachings, there should not be any war. As long as a person is involved with warfare, trying to defend or attack, then the action is not sacred; it is mundane, dualistic, a battlefield situation. One would not expect the great teachings to be as simple-minded as that, trying to be good, fighting the bad. Sense of humor means seeing both poles of a situation as they are, from an aerial point of view. There is good, there is bad, and you see both with a panoramic view.
