Translation: "Arjuna said: O killer of Madhu (Kṛṣṇa), how can I counterattack with arrows in battle men like Bhīṣma and Droṇa, who are worthy of my worship? It is better to live in this world by begging than to live at the cost of the lives of great souls who are my teachers. Even though they are avaricious, they are nonetheless superiors. If they are killed, our spoils will be tainted with blood."
Prabhupāda: So the first problem was for Arjuna how to kill the kinsmen, family men. Now, when he was chastised by Kṛṣṇa as a friend that "Why you are so weak? Don't be weak. This is sentiment. This kind of compassion is sentiment. Uttiṣṭha. You better get up and fight." If I do not want to do something, I can offer so many pleas. You see. So next he is presenting gurūn: "All right, Kṛṣṇa, you are talking about my kinsmen. I accept that it is my weakness. But how do You advise me to kill my guru? Droṇācārya is my guru. And Bhīṣmadeva is also my guru. So do you want me to kill my guru? Gurūn hi hatvā. And not only ordinary guru. This is not that they are ordinary men. Mahānubhāvān. Bhīṣma is a great devotee, and similarly, Droṇācārya also, a great personality. Mahānubhāvān. So kathaṁ bhīṣmam ahaṁ saṅkhye droṇaṁ ca madhusūdana (BG 2.4). "They are two great personalities. They are not only my gurus, but they are great personalities." And Kṛṣṇa is addressed "Madhusūdana." Madhusūdana means... Madhu was Kṛṣṇa's enemy, a demon. So He killed. So "You are Madhusūdana, You are killer of Your enemies. Can You give me any evidence that You have killed Your guru? So why You are asking me?" This is the purport. Iṣubhiḥ pratiyotsyāmi pūjārhāv ari-sūdana. Again Ari-sūdana. Ari means enemy. Madhusūdana, particularly "the killer of the Madhu demon." And next is Arisudana. Ari means enemy. So Kṛṣṇa has killed so many demons, ari, who came to fight with Him as enemy. Therefore His name is Arisudana.
So Kṛṣṇa has got enemies also, what to speak of ourself. This material world is so made, that you must have some enemies. Matsaratā. Matsaratā means enviousness, jealousy. This material world is like that. So there are jealous enemies of God also. They are called demons. Ordinary jealousy or enemy, that is natural. But even to God. Just like yesterday night, evening, somebody came to see me. He was arguing that "Why Kṛṣṇa should be accepted as God?" That was his argument. So Kṛṣṇa has enemies. Therefore Kṛṣṇa... Not only He, but everyone who is in the material world is enemy of Kṛṣṇa. Everyone. Because they want to be competitor of Kṛṣṇa.
