Thy ill fame, in consequence of the slaughter of Drona, will be eternal in the three worlds with their mobile and immobile creatures, like Rama's in consequence of the slaughter of Bali! About thyself, Drona had thought, 'The son of Pandu is possessed of every virtue; he is, besides, my disciple. He will never speak an untruth to me.' Thinking so, he gave credence to what thou hadst said. Although in speaking of Aswatthaman's death thou hadst added the world elephant, yet thy answer to the preceptor was, after all, an untruth in the garb of truth. Thus told by thee, the puissant Drona laid aside his weapons and, as thou sawest, became indifferent (to everything), exceedingly agitated, and almost deprived of his senses. It was even a disciple who, abandoning all morality, thus slew his own preceptor, full of affection for his son, while, indeed, that preceptor was filled with grief and unwilling to fight. Having caused him, who had laid his weapons to be unrighteously slain, protect the son of Prishata if thou canst, with all thy counsellors. All of us, uniting together, shall not be able to protect Prishata's son today, who will be assailed by the preceptor's son in wrath and grief. That superhuman being who is in that habit of displaying his friendship for all creatures, that hero, hearing of the seizure of his sire's locks, will certainly consume us all in battle today.
