Prabhupāda: Of course, all explanation are not there. Here, these words, Kṛṣṇa addressed Arjuna, "chastiser of enemies." And Arjuna addresses Kṛṣṇa, "Madhusūdana," or the killer of the demon Madhu. "Yes, You are addressing me as chastiser of enemy, but do You think my grandfather, my teacher, they are my enemies? You killed demon Madhu, therefore Your name is Madhusūdana, but You are asking me to kill my grandfather and teacher." That is the hint. "It is all right that Your name is Madhusūdana. You killed one demon whose name was Madhu, but You are asking me, Bhīṣmasūdana? Bhīṣma is my grandfather. And Droṇasūdana?" Sūdana means killer. "So how can I be that?" That is the answer.
Tamāla Kṛṣṇa: "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, then our spoils will be tainted with blood (BG 2.5)."
Prabhupāda: This is another indication how superiors should be shown respect. Arjuna says, "Although they have become avaricious, still, they are my superior." Avaricious, why? "They have got full affection for me. My grandfather Bhīṣma has got full affection for me. And Droṇācārya, I am his very dear student so he has also my very affection... good affection for me. But because Duryodhana has paid them, he has accepted their service. Paid them. So avaricious. Simply for money, in spite of so much affection and intimate relationship, they have accepted the service of Duryodhana, counting on money. So therefore they are avaricious. But in spite of their being avaricious, they are my respectful." This is respect. This is respect, that the respectful person who is my respectful, even there are some characteristics who does not command respect, still respect should be offered. This is a respectful offering. Yes. Sometimes it may be.
