When we were walking, the question was raised that "Why war takes place?" That is not a very difficult subject to understand, because every one of us has got a fighting spirit. Even children fight, cats and dogs fight, birds fight, ants fight. We have seen it. So why not human being? The fighting spirit is there. That is one of the symptoms of living condition: fighting. So when that fighting should take place? Of course, at the present moment, by the ambitious politicians they fight. But fighting, according to Vedic civilization, fighting means dharma-yuddha, on religious principle. Not by whims of political ideas, "ism."
Fighting you cannot stop. Many people, they are thinking how to stop war. That is impossible. It is nonsense proposal. It cannot be. Because the fighting spirit is there in everyone. That is a symptom of living entity. Even children, who has no politics, no enmity, they fight for five minutes; again they are friends. So the fighting spirit is there.
Now, how it should be utilized? Our Krsna consciousness movement is there. We say "consciousness." We don't say, "Stop fight" or "Do this, do that, do that," no. Everything should be done in Krsna consciousness. That is our propaganda.
