Yonder the troops of the Pandavas and the Srinjayas, united together, are now rushing against me. For achieving thy good in battle, O son of Dhritarashtra, I will not without slaying all the Panchalas, put off my armour. O king, go and tell my son Aswatthaman who is present in battle that even at the risk of his life he should not let the Somakas alone.[186] Thou shouldst also tell him, ‘Observe all the instructions thou hast received from thy father. Be firm in acts of humility, in self-restraint, in truth and righteousness. Observant of religion, profit, and pleasure, without neglecting religion and profit, thou shouldst always accomplish those acts in which religion predominates. The Brahmanas should always be gratified with presents. All of them deserve thy worship. Thou shouldst never do anything that is injurious to them. They are like flames of fire.’ As regards myself, I will penetrate the hostile host, O slayer of foes, for doing great battle, pierced as I am by thee with thy wordy shafts. If thou canst, O Duryodhana, go and protect those troops. Both the Kurus and the Srinjayas have been angry. They will fight even during the night.” Having said these words, Drona proceeded against the Pandavas and set himself to over-ride the energy of the Kshatriyas like the sun overshadowing the light of the stars.’”
