There is no question of Arjuna's considering whether he would fight or not. It is sanctioned by Kṛṣṇa; so fight must be there. Just like 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."
Just like now fighting is going on on two political groups, the Communist and the capitalist. They are trying to avoid only fight, but the fighting is going on. As soon as America is in some field, immediately Russia is also there. In the last fighting between India and Pakistan, as soon as President Nixon sent their Seventh Fleet on the Indian Ocean, Bay of Bengal, almost in front of India . . . this was illegal. But very puffed-up, America, so sent the Seventh Fleet, maybe to show sympathy the Pakistan. But immediately our Russian friend also appeared there, therefore America had to come back. Otherwise, I think America would have attacked on behalf of Pakistan.
So this is going on. 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 you should be utilized? Our Kṛṣṇa 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 Kṛṣṇa consciousness. That is our propaganda. Nirbandha-kṛṣṇa-sambandhe (Bhakti-rasāmṛta-sindhu 1.2.255). Whatever you do, it must have some relationship with the satisfaction of Kṛṣṇa. If Kṛṣṇa is satisfied, then you act. That is Kṛṣṇa consciousness. Kṛṣṇendriya tṛpti vāñchā tāra nāma prema (CC Adi 4.165). This is love. Just like you love somebody; for the sake of your beloved, you can do anything. And we do sometimes. Similarly, the same thing should be transferred to Kṛṣṇa. That's all.
Try to educate yourself how to love Kṛṣṇa and act for Kṛṣṇa only. This is the perfection of life. Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). Bhakti, bhakti means service, bhaja-sevāyām. The bhaja-dhātu, it is used for the purpose of rendering service, bhaja. And bhaja, there is Sanskrit grammar, kti-pratyaya, to make it noun. This is verb. So there are pratyayas, kti pratyaya, ti pratyaya, many pratyayas. So bhaj-dhātu kti, equal to bhakti.
