“Sanjaya continued, ‘Thus rebuked and angered by thy son, Drona, O king, wrathfully addressed Duryodhana and said these words: “Although I am so old, O Duryodhana, I am still exerting myself in battle to the utmost extent of might. All these men are unacquainted with weapons. I am, however, well-versed in them. If, from desire of victory, I slay these men, there can be no more ignoble act for me to do. That, however, which is in thy mind, be it good or bad, I will accomplish, O Kaurava, at thy command. It will not be otherwise. Putting forth my prowess in battle and slaying all the Panchalas, I will doff my armour, O king! I swear this to thee truly. Thou thinkest that Arjuna, the son of Kunti, was worn out in battle. O mighty-armed Kaurava! Listen to what I truly say regarding his prowess. If Savyasachin’s wrath is excited, neither Gandharvas, nor Yakshas nor Rakshasas can venture to bear him. At Khandavas, he encountered the divine chief of the celestials himself. The illustrious Arjuna, with his shafts baffled the pouring Indra. Yakshas, and Nagas, and Daityas, and all others proud of their might, were slain by that foremost of men. That also is known to thee. On the occasion of the tale of cattle, the Gandharvas headed by Chitrasena and others were vanquished by him. That firm bowman rescued you, while you were being carried away by those Gandharvas. Nivatakavachas also, those enemies of the celestials, that were unslayable in battle by the celestials, themselves, were vanquished by that hero. Thousands of Danavas dwelling in Hiranyapura, that tiger among men vanquished. How can human beings then withstand him? O monarch, thou hast seen with thy own eyes how this host of thine, although exerting themselves so heroically, hath been destroyed by the son of Pandu.”’
