All those mighty persons, skilled in arriving at conclusions in council, coolly deliberated about that which was beneficial for them in view of their immediate circumstances. Then king Yudhishthira, having reflected for a long while, said these words, casting his eyes on Vasudeva, 'Behold, O Krishna, the high-souled Bhishma of fierce prowess. He crusheth my troops like an elephant crushing a forest of reeds. We dare not even look at that high-souled warrior. Like a raging conflagration he licketh up my troops. The valiant Bhishma of keen weapons, when excited with wrath in battle and bow in hand shooting his shafts, becometh as fierce as the mighty Naga Takshaka of virulent poison. Indeed, the angry Yama is capable of being vanquished, or even the chief of the celestials armed with the thunder, or Varuna himself, noose in hand, or the Lord of the Yakshas armed with mace. But Bhishma, excited with wrath, is incapable of being vanquished in battle. When this is the case, O Krishna, I am, through the weakness of my understanding, plunged in an ocean of grief having got Bhishma (as a foe) in battle. I will retire into the woods, O invincible one. My exile there would be for my benefit. Battle, O Krishna, I no longer desire. Bhishma slayeth us always. As an insect, by rushing into a blazing fire meeteth only with death, even so do I rush upon Bhishma. In putting forth prowess, O thou of Vrishni's race, for the sake of my kingdom, I am, alas, led to destruction.
