The word praja-sarga is very important in this verse. When the saintly King Pracinabarhi was induced by the great sage Narada to leave home and take to the devotional service of the Lord, his sons had not yet returned from their austerities in the water. However, he did not wait for their return but simply left messages to the effect that his sons were to protect the mass of citizens. According to Viraraghava Acarya, such protection means organizing the citizens into the specific divisions of the four varnas and four asramas. It was the responsibility of the royal order to see that the citizens were following the regulative principles of the four varnas (namely brahmana, ksatriya, vaisya and sudra) and the asramas (namely brahmacarya, grhastha, vanaprastha and sannyasa). It is very difficult to rule citizens in a kingdom without organizing this varnasrama-dharma. To rule the mass of citizens in a state and keep them in a complete progressive order is not possible simply by passing laws every year in a legislative assembly. The varnasrama-dharma is essential in a good government. One class of men (the brahmanas) must be intelligent and brahminically qualified, another class must be trained in administrative work (ksatriya), another in mercantile business (vaisya) and another simply in labor (sudra). These four classes of men are already there according to nature, but it is the governments duty to see that all four of these classes follow the principles of their varnas methodically. This is called abhiraksana, or protection.
