Tamāla Kṛṣṇa: "The kṛpaṇas, or miserly persons, waste their time in being overly affectionate for family, society, country, etc., in the material conception of life. One is often attached to family life, to wife and children and other members on the basis of 'skin disease.' The kṛpaṇas think that they are able to protect their family members from death, or the kṛpaṇa thinks that his family or society can save him from death. Such family attachment can be found even in the lower animals, who also take care of children. Being intelligent, Arjuna could understand that his affection for family members and his wish to protect them from death were the causes of his perplexities. Although he could understand that his duty to fight was awaiting him, still on account of miserly weakness he could not discharge the duty. He is therefore asking Lord Kṛṣṇa, the supreme spiritual master, to make a definite solution. He offers himself to Kṛṣṇa as a disciple. He wants to stop friendly talks. Talks between a master and disciple are serious, and now Arjuna wants to talk very seriously before the recognized spiritual master. Kṛṣṇa is therefore the original..."
Prabhupāda: Here is a technique. The same Kṛṣṇa and same Arjuna, they are talking as friends. Then what was the necessity of Arjuna accepting Kṛṣṇa as spiritual master? The same Arjuna and same Kṛṣṇa, they'll talk, but what is the necessity of accepting as spiritual master? That means after accepting spiritual master he'll not argue. He'll simply accept whatever He says. That is the technique. Friendly talks, equal level, He, Kṛṣṇa was talking something and he was replying. So that argument has no end. But when he accepts Him as spiritual master, there is no more argument. One has to accept whatever He says. Therefore he's accepting as spiritual master. After this, Arjuna will never say, "This is wrong, this is, no," or "I don't agree." No. He'll accept. So acceptance of spiritual master means to accept anything, whatever he says. Therefore one has to select a spiritual master whom he can completely surrender. That is the technique. Veda-vākya.
