Within each yojana have been established one and twenty posts of armed men. And at intervals of each yojana are hundred gates with arches which are defended by valourous heroes engaged in guarding them. And innumerable Kshatriyas invincible in war, belonging to the eighteen younger branches of the Yadavas, are employed in defending these works. In our race, O king, there are full eighteen thousand brothers and cousins. Ahuka hath had a hundred sons, each of whom is almost like a god (in prowess), Charudeshna with his brother Chakradeva, Satyaki, myself, Valadeva the son of Rohini, and my son Samva who is equal unto me in battle--these seven, O king are Atirathas. Besides these, there are others, O king, whom I shall presently name. They are Kritavarman, Anadhrishti, Samika, Samitinjaya, Kanka, Sanku and Kunti. These seven are Maharathas. There are also two sons of Andhakabhoja, and the old king himself. Endued with great energy these are all heroes, each mighty as the thunderbolt. These Maharathas, choosing the middle country, are now living amongst the Vrishnis. O thou best of the Bharata line, thou alone art worthy of being an emperor. It behoveth thee, O Bharata, to establish thy empire over all the Kshatriyas. But this is my judgment, O king, that thou wilt not be able to celebrate the Rajasuya sacrifice as long as the mighty Jarasandha liveth.
