Since a ksatriya king naturally desires to rule the world, he wishes to make all other kings subordinate to him. This was also the position many years ago when Prthu Maharaja was ruling over the earth. At that time he was the only emperor on this planet. Even five thousand years ago, Maharaja Yudhisthira and Maharaja Pariksit were the sole emperors of this planet. Sometimes the subordinate kings rebelled, and it was necessary for the emperor to go and chastise them. This process of chanting the narrations of the life and character of Prthu Maharaja is recommended for conquering kings if they want to fulfill their desire to rule the world.
