chādayitvā tato bāṇaiḥ karṇaṃ prabhrāmya cārjunaḥ |
tasya karṇaḥ śaraiḥ kruddhaściccheda jyāṃ sutejanaiḥ || 53 ||

The son of Radha baffles thy shafts." With proper mantras, Arjuna then fixed the brahmastra on his string, and shrouding all the points of the compass with arrows, Partha struck Karna (with many) arrows. Then Karna, with a number of whetted shafts endued with great energy, cut off the string of Arjuna's bow. Similarly he cut off the second string, and then the third, and then the fourth, and then the fifth. The sixth also was cut off by Vrisha, and then the seventh, then the eighth, then the ninth, then the tenth, and then at last the eleventh. Capable of shooting hundreds upon hundreds of arrows, Karna knew not that Partha had a hundred strings to his bow. Tying another string to his bow and shooting many arrows, the son of Pandu covered Karna with shafts that resembled snakes of blazing mouths. So quickly did Arjuna replace each broken string that Karna could not mark when it was broken and when replaced. The feat seemed to him to be exceedingly wonderful. The son of Radha baffled with his own weapons those of Savyasaci. Displaying also his own prowess, he seemed to get the better of Dhananjaya at that time.
