Prabhupāda: Universal morality is to obey God, that's all. This is universal morality.
Śyāmasundara: But are any of God's laws fixed...
Prabhupāda: That is included. If you obey God, then all the laws are also included. That is the universal morality. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru: (BG 18.65) "Just become My servitor, always think of Me, just offer obeisances unto Me," that is morality.
Śyāmasundara: Oh, that's the basis for morality?
Prabhupāda: Yes. Otherwise, there are so many immoral things going on that are accepted as morality. How can you find out?
Śyāmasundara: He says that there are...
Prabhupāda: I do not wish to say that in the Koran it is said that "From this day you should stop intercourse with mother."
Śyāmasundara: He says that there are...
Prabhupāda: Does it not say in the Koran? Yes. I've seen one Koran translation. Such a society. Similarly, Lord Jesus Christ said that "You shall not kill." So, so many immoral things are going on that are accepted as not sinful.
Śyāmasundara: He recognizes this, and he says that there are certain imperatives that we are born with, that we know are...
Prabhupāda: What are these? He should say practically. The certain, imperative morality is this: that you should be obedient to God. That's all.
