Tamāla Kṛṣṇa: "Nor do we know which is better, conquering them or being conquered by them. The sons of Dhṛtarāṣṭra, whom if we killed we should not care to live, are now standing before us on this battlefield (BG 2.6)." Purport. "Arjuna became perplexed in this connection, not knowing whether he should execute the fighting with the risk of committing unnecessarily violence, although it is the duty of the kṣatriyas, or whether he should not and prefer instead to live by begging, because if he did not conquer the enemy, begging would be the only means left for his living. There was no certainty of victory because either side might emerge victorious."
Prabhupāda: These are his causes of perplexities, how he was thinking, that has been tried to be explained. Yes, go on.
