Dharmyāddhi-yuddha. There are two kinds of of fighting. Dharma-yuddha. Dharma-yuddha means right, righteous fighting, and adharma-yuddha means political. That is... One politician, he wants to keep his position, he engages the people in fighting, declares war. That is another thing. But when right thing, violence is required. So Arjuna... Kṛṣṇa is encouraging Arjuna in dharma-yuddha, not unnecessarily killing in the slaughterhouse. Do not misunderstand Kṛṣṇa. The rascals, they misunderstand. By killing, by his whims, he gives the evidence of... Another rascal, although he is learned professor, he says that because this man has killed on the basis of Bhagavad-gītā, therefore Kṛṣṇa is immoral. Just see. This is going on. Without understanding Bhagavad-gītā, even a so-called learned scholar also talking of Kṛṣṇa as immoral. He has encouraged killing. Just see. Such envious persons. And he is teaching Bhagavad-gītā. This is going on.
So this is not the fact. The fact is that there must be in the society, four classes of men. Because sometimes violence is required. Just like why government is maintaining the police force, the military force? It is required for keeping law and order. So violence is bad. That's all right. But sometimes it is required.
