The states duty and the citizens duty are very nicely explained in this verse. The activities of the government head, or king, as well as the activities of the citizens, should be so directed that ultimately everyone engages in devotional service to the Supreme Personality of Godhead. The king, or government head, is supposed to be the representative of the Supreme Personality of Godhead and is therefore supposed to see that things go on nicely and that the citizens are situated in the scientific social order comprised of four varnas and four asramas. In the Visnu Purana it is stated that unless people are educated or situated in the scientific social order comprised of four varnas (brahmana, ksatriya, vaisya and sudra) and four asramas (brahmacarya, grhastha, vanaprastha and sannyasa), society can never be considered real human society, nor can it make any advancement towards the ultimate goal of human life. It is the duty of the government to see that things go on in terms of varna and asrama. As stated herein, bhagavan yajna-purusahthe Supreme Personality of Godhead, Krsna, is the yajna-purusa. As stated in Bhagavad-gita (5.29): bhoktaram yajna-tapasam. Krsna is the ultimate purpose of all sacrifice. He is also the enjoyer of all sacrifices; therefore He is known as yajna-purusa. The word yajna-purusa indicates Lord Visnu or Lord Krsna, or any Personality of Godhead in the category of visnu-tattva. In perfect human society, people are situated in the orders of varna and asrama and are engaged in worshiping Lord Visnu by their respective activities. Every citizen engaged in an occupation renders service by the resultant actions of his activities. That is the perfection of life. As stated in Bhagavad-gita (18.46):
