The form, O king, of Bhimasena in that battle looked like that of a mountain in the evening when covered with fire. That weapon of Drona's son, directed against Bhimasena increased in energy and might, [paragraph continues] O king, like a conflagration assisted by the wind. Beholding that weapon of terrible energy thus increasing in might, a panic entered the hearts of all the combatants of the Pandava army with the exception of Bhima. Then all of them, throwing down their weapons on the earth, alighted from their cars and steeds. After they had thrown their weapons and alighted from their vehicles, that weapon of exceeding energy fell upon the head of Bhima. All creatures, especially the Pandavas, uttered cries of Oh and Alas, beholding Bhimasena overwhelmed by the energy of that weapon.'"
