tatra gacchasva rāma tvaṃ tvaritaṃ yuddhadurmada |
vyapaneṣyāmi te darpaṃ paurāṇaṃ brāhmaṇabruva || 35 ||

There, O Rama, where in days of yore thou hadst propitiated thy (deceased) fathers (with oblations of Kshatriya blood), slaying thee there, O son of Bhrigu, I will propitiate the Kshatriya slain by thee! Come there, O Rama, without delay! There, O thou that art difficult of being vanquished, I will curb thy old pride about which the Brahmanas speak! For many long years, O Rama, thou hast boasted, saying,--I have, single-handed, vanquished all the Kshatriyas of the Earth!--Listen now to what enabled thee to indulge in that boast! In those days no Bhishma was born, or no Kshatriyas like unto Bhishma! Kshatriyas really endued with valour have taken their births later on! As regards thyself, thou hast consumed only heaps of straw! The person that would easily quell thy pride of battle hath since been born! He, O mighty-armed one, is no other than myself, even Bhishma, that subjugator of hostile cities! Without doubt, O Rama, I shall just quell thy pride of battle!'
