Mahabharata Drona Parva Chapter 200:2

Mahabharata Drona Parva (Drona-vadha Parva) Chapter 200:2 Having crossed the Bhishma and the Drona oceans in this battle, that are incapable of being crossed by the timid, shall I sink with all my followers in the vestige, represented by Drona's son, of a cow's hoof? Let the wishes of king Duryodhana be crowned with success today, for I have today slain in battle the preceptor, that always cherished such friendly feelings towards us, that preceptor, who, without protecting, caused that child unacquainted with battle, viz., the son of Subhadra, to be slain by a multitude of wicked warriors, that preceptor, who with his son, sat indifferently, without answering, when Krishna in such distress, dragged into the assembly and sought to be made a slave, asked him to say the truth, that preceptor, who, while all the other warriors were fatigued, cased Duryodhana in invulnerable armour when the latter desired to slay Phalguna and who, having cased him so, appointed him to protect Jayadratha, who, being acquainted with the Brahma weapon, scrupled not to exterminate the Panchalas, headed by Satyajit, that had exerted themselves for my victory, that preceptor, who, whilst we were being unrighteously exiled from our kingdom, freely told us to go into the woods although he had been solicited by our friends to withhold his permission. Alas, that great friend of our hath been slain! For his sake, I will, with my friends, lay down my life. After Kunti's son, Yudhishthira had said this, he of Dasarha's race, (viz., Kesava) quickly forbidding the troops, by motion of his arms, to fly away said these words, "Speedily lay down your weapons, all of you, and alight from your vehicles. Even this is the means ordained by the illustrious one, (viz., Narayana himself) for baffling this weapon. Come down on the earth, all of you from your elephants and steeds and cars. If you stand weaponless on the earth, this weapon will not slay you. In those places where you will fight for quelling the force of this weapon the Kauravas will become more powerful than you. Those men, however, that will throw down their weapons and alight from their vehicles, will not in this battle, be slain by this weapon. They, however, that will, even in imagination, contend against this weapon, will all be slain even if they seek refuge deep beneath the earth". The warriors of the Pandava army, hearing, O Bharata, these words of Vasudeva, threw their weapons and drove away from their hearts all desire of battle. Then Bhimasena, the son of Pandu, beholding the warriors about to abandon their weapons, said these words, O king, gladdening them all: "None should lay down his weapons here. I shall, with my shafts, oppose this weapon of Drona's son. With this heavy mace of mine, that is decked with gold, I shall career in this battle like the Destroyer himself, quelling this weapon of Drona's son. There is no man here that is equal to me in prowess, even as there is no luminary in the firmament that is equal to the sun.
