In the reign of King Pṛithu, people were long lived, wealthy, had peacful relations with their neighbours. None was wicked, poor or sick. In the glorious reign of Pṛithu, there was no phenomenon foreboding evil that would have caused consternation to his subjects. Every one passed his days in perfect peace and contentment, without getting overcome by grief or pain. Pṛithu, the Great, by the power of his bow, made many a part of his extensive Empire habitable and culturable. During the time of that valiant monarch, there was no need of a fortress, it was not necessary for the people to arm themselves, the science of political economy was not in vogue. It was simply lying unhonoured. All the people performed their duties and prescribed rites. "I have explained to you, O King! how they milked the earth and got out of it what they wished, from which it must be understood that, at the time of performing sacrificial rites, the thing that each got out of the earth should be offered to him." The learned also call the land Pṛithvî because it was milked by the old King Pṛithu, the righteous.—23-35.
