It is for this that men desire for a worthy son, and that preceptor seeks a pupil who would contradict him not. It is for this that the time is come for that excellent work, which is the best of all tasks and difficult to perform. I shall baffle Duryodhana's volleys of arms by my own excellent weapons. I shall overpower all in the field of battle. I shall in my wrath cut off his head with my excellent shafts, little inferior to snakes and poison and fire. And with the keen edge of my sword, I shall forcibly sever his head from the trunk, in the field of battle; then I shall kill his followers, and Duryodhana, and all of Kuru's race. O son of Rohini! let the followers of Bhima look at me with joy at their heart, when I shall keep up the weapons of war in the field of battle, and when I shall go on slaying all the best fighting men on the side of the Kurus, as at the end of time fire will burn vast heaps of straw. Kripa and Drona and Vikarna and Kama are not able to bear the keen arrows shot by Pradyumna. I know the power of Arjuna's son--he conducts himself like the son of Krishna in the field of battle. Let Samva chastise by the force of his arms Dussasana; let him destroy by force Dussasana and his charioteer and his car. In the field of battle when the son of Jamvavati becomes irresistible in fight, there is nothing which can withstand his force. The army of the demon Samvara was speedily routed by him when only a boy.
