He said that "After killing my family men..." Dhṛtarāṣṭra, dhārtarāṣṭrāḥ, pāṇḍavāḥ... Dhṛtarāṣṭra and Pāṇḍu, they were two brothers, and their sons, cousin-brothers. So generally, people want to increase his material opulence to show to his friends and relatives. When one person constructs a very new, very nice house, he invites his relatives and his friends to show them that "Now I have become so opulent." So Arjuna is thinking in that term, that "Suppose I conquer over and I get the kingdom. But if my relatives and brothers are dead, whom shall I show?" This is another kind of vairāgya. How this material relationship makes one foolish, Arjuna is playing the part of a foolish man, and Kṛṣṇa will chastise him. We shall see later on. Thank you very much. Hare Kṛṣṇa.
