Mbh 2.15.3a

“Krishna then said,--‘One that is immature in understanding seeketh the fruition of his desire without an eye to what may happen to him in future. It is seen that no one forgiveth for that reason a foe that is of immature understanding and inclined to serve his own interests. It hath been heard by us that in the krita age, having brought every one under their subjection, Yauvanaswin by the abolition of all taxes, Bhagiratha by his kind treatment to his subjects, Kartavirya by the energy of his asceticism, the lord Bharata by his strength and valour, and Maruta by his prosperity, all these five became emperors. But, O Yudhishthira, thou who covetest the imperial dignity deserves it, not by one but by all these qualities, viz., victory, protection afforded to thy people, virtue, prosperity, and policy. Know, O bull of the Kuru race, that Jarasandha, the son of Vrihadratha, is even such (i.e., a candidate for the imperial dignity). A hundred dynasties of kings have become unable to oppose Jarasandha. He, therefore, may be regarded to be an emperor for his strength. Kings that are wearers of jewels worship Jarasandha (with presents of jewels). But, wicked from his childhood, he is scarcely satisfied with such worship. Having become the foremost among all, he attacketh yet with violence kings with crowns on their heads. Nor is there seen any king from whom he taketh not tribute. Thus hath he brought under his sway nearly a hundred kings. How can, O son of Pritha, any weak monarch approach him with hostile intentions? Confined in the temple of Shiva and offered as sacrifice unto him like so many animals, do not these monarchs dedicated unto that god feel the most poignant misery, O bull of the Bharata race? A Kshatriya that dieth in battle is ever regarded with respect. Why shall we not, therefore, meet together and oppose Jarsandha in battle? He hath already brought eighty-six kings; fourteen only are wanting to complete one hundred.
