Srimad Bhagavatam Canto 04, Chapter 23, Text 36

SB 4.23.36

vijayabhimukho raja
 srutvaitad abhiyati yan
balim tasmai haranty agre
 rajanah prthave yatha
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
If a king, who is desirous of attaining victory and ruling power, chants the narration of Prthu Maharaja three times before going forth on his chariot, all subordinate kings will automatically render all kinds of taxes unto him — as they rendered them unto Maharaja Prthu — simply upon his order.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
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.
