Śyāmasundara: He says that the moral sentiments which are approved by society enhance the social good, whereas immoral attitudes are egoistic and antisocial. So that a society will always approve of a certain set of moral values, and then the individual living in the society must either accept or reject them. And if he rejects them, then he must act through politics, through the social body, to try to change their attitude, their opinion.
Prabhupāda: Therefore it depends on that social body, which is authority. So ultimately we have to depend on the authority for all sanctions. So our proposition is that the supreme authority is Kṛṣṇa. So whatever He sanctions, that is morality; whatever He does not sanction, that is immorality. Just like Arjuna was thinking to become nonviolent, not to fight, is good. But Kṛṣṇa said, "Now you fight." So fight became good. So ultimately it depends on Kṛṣṇa's will, what is morality, what is immorality, what is good, what is bad. Therefore our duty is, instead of depending on social body or political... (break) ...are so many, one is different from the other—we depend on the supreme will of the supreme authority.
Śyāmasundara: He says that there is no absolute morality, that everything is relative.
Prabhupāda: Yes. We say also. If it is sanctioned by Kṛṣṇa, then it is morality; otherwise the same morality may be immorality. Just like Yudhiṣṭhira was asked by Kṛṣṇa to speak lie—"Go to Droṇācārya and inform him that 'Your son is dead,' " because Droṇācārya had a benediction that unless he was shocked by the dead limbs of his son, he would not die. So he had to be shocked. But he would not believe anybody except King Yudhiṣṭhira because he was known as very honest and truthful. Therefore Kṛṣṇa employed this service that "You go." Mahārāja Yudhiṣṭhira, he said, "Oh, how can I tell a lie?" So this is immorality. Kṛṣṇa is ordering, and he is saying that "How can I say lie?" This is immorality; he is disobeying the order of Kṛṣṇa. But Arjuna, he rejected all morality and immorality. He accepted Kṛṣṇa's order. That is morality.
