(Prabhupada's lecture - Śrīmad-Bhāgavatam 1.16.12 - Los Angeles, January 9, 1974)
So in order to save the human society from this dangerous condition, without any knowledge of God, without any knowledge of religious principle, there must be some strong king, strong government, to save the people. Because this human life is a chance. Other inferior type of life, animals, birds, beasts, trees, it is not possible. They are also living entities, but human life is developed consciousness. So this is nature's gift, that "Now you try to understand what is God. Now you try to understand what is your relationship with God. Now you practice yourself, how to go back home, back to home, back to..." This is the business of the human society.
So unless the king or government looks after it, how people will be advanced? The government is advocating that "You drink, you eat meat, you have prostitution and gambling, and give me tax. Finished. My business is finished." So Parīkṣit Mahārāja was not like that. Parīkṣit Mahārāja is conquered all these places to serve Kṛṣṇa, to teach Kṛṣṇa consciousness. Therefore he conquered. Otherwise... That is the business of all devotees.
