so'haṃ śvastatkariṣyāmi yathā kuntīsuto'rjunaḥ |
aprāpte'staṃ dinakare haniṣyati jayadratham || 22 ||

If we have achieved any (religious) merit, if we have ever poured libations of clarified butter into fire, let Savyasachin, aided by the fruits thereof, vanquish all his foes.' Thus talking, O lord, with one another about the victory (of the morrow), that long night, O king, of theirs, at last, passed away. In the middle of the night, Janardana, having awaked, remembered Partha's vow, and addressing (his charioteer) Daruka, said, 'Arjuna, in grief for the death of his son, hath vowed. O Daruka, that before tomorrow's sun goes down he will slay Jayadratha. Hearing of this, Duryodhana will assuredly take counsel with his counsellors, about how Partha may fail to achieve his object. His several Akshauhinis of troops will protect Jayadratha. Fully conversant with the ways of applying all weapons, Drona also, with his son, will protect him. That matchless hero, the Thousand-eyed (Indra himself), that crusher of the pride of Daityas and Danavas cannot venture to slay him in battle who is protected by Drona. I, therefore, will do that tomorrow by which Arjuna, the son of Kunti, may slay Jayadratha before the sun sets. My wives, my kinsmen, my relatives, non amongst these is dearer to me than Arjuna. O Daruka, I shall not be able to cast my eyes, even for a single moment, on the earth bereft of Arjuna. I tell thee, the earth shall not be reft to Arjuna.
