No doubt, you will, before long, rule over men in a praiseworthy way, all your desires being fulfilled. Here are we prepared to chastise the Kurus, as soon as the stipulation made by you is fully performed! And Krishna, the foremost of the Dasarha tribe, then said to Dhaumya and Bhima and Yudhishthira, and the twins and Krishna, ‘How fortunate that by your blessing Arjuna the bearer of the coronet, has arrived after having acquired the science of arms!” And Krishna, the leader of the Dasarha tribe, accompanied by friends, likewise spoke to Krishna, the daughter of Yajnasena, saying, ‘How fortunate that you are united, safe and secure, with Arjuna, the winner of riches!’ And Krishna also said, ‘O Krishna, O daughter of Yajnasena, those sons of yours, are devoted to the study of the science of arms, are well-behaved and conduct themselves on the pattern, O Krishna, of their righteous friends. Your father and your uterine brothers proffer them a kingdom and territories; but the boys find no joy in the house of Drupada, or in that of their maternal uncles. Safely proceeding to the land of the Anartas, they take the greatest delight in the study of the science of arms. Your sons enter the town of the Vrishnis and take an immediate liking to the people there. And as you would direct them to conduct themselves, or as the respected Kunti would do, so does Subhadra direct them in a watchful way. Perhaps, she is still more careful of them. And, O Krishna, as Rukmini’s son is the preceptor of Aniruddha, of Abhimanyu, of Sunitha, and of Bhanu; so he is the preceptor and the refuge of your sons also! And a good preceptor, would unceasingly give them lessons in the wielding of maces and swords and bucklers, in missiles and in the arts of driving cars and of riding horses, being valiant.
