Indeed, urged by Bhima and Janardana, and recollecting (his woes), and taking an internal survey of himself, and calling to mind the object for which he had come to this world, he addressed Keshava, saying, "I will now invoke into existence a mighty and fierce weapon for the good of the world and the destruction of the Suta's son. Let me have thy permission, as also Brahman's and Bhava's, and of all those that are conversant with Brahma." Having said these words unto the holy Keshava, Savyasaci of immeasurable soul bowed unto Brahman and invoked into existence that excellent irresistible weapon called brahmastra which could be applied by the mind alone. Baffling that weapon, however, Karna looked beautiful as he continued, like a cloud pouring torrents of rain, to shoot his shafts. Beholding that weapon of the diadem-decked Arjuna baffled in the midst of battle by Karna, the wrathful and mighty Bhima, blazing up with rage, addressed Arjuna of sure aim and said, "People say that thou art a master of the high brahmastra, that mighty means (for achieving the destruction of foes). Do thou then, O Savyasaci, use another weapon of the same kind." Thus addressed by his brother, Savyasaci used a second weapon of the kind. With that, Partha of abundant energy shrouded all the points of the compass, cardinal and subsidiary, with arrows sped from gandiva that resembled fierce snakes and were like the blazing rays of the sun.
