śarairvibhugnaṃ vyasu tadvivarmaṇaḥ papāta karṇasya śarīramucchritam |
sravadvraṇaṃ gairikatoyavisravaṃ gireryathā vajrahataṃ śirastathā || 26 ||

Thus sped by that mighty warrior, that shaft endued with the energy of the sun caused all the points of the compass to blaze up with light. With that weapon Arjuna struck off his enemy's head like Indra striking off the head of Vritra with his thunder. Indeed, O king, with that excellent Anjalika weapon inspired with mantras into a mighty weapon, the son of Indra cut off the head of Vaikartana in the afternoon. Thus cut off with that Anjalika, the trunk of Karna fell down on the earth. The head also of that commander of the (Kaurava) army, endued with splendour equal to that of the risen sun and resembling the meridian sun of autumn, fell down on the earth like the sun of bloody disc dropped down from the Asta hills. Indeed, that head abandoned with great unwillingness the body, exceedingly beautiful and always nursed in luxury, of Karna of noble deeds, like an owner abandoning with great unwillingness his commodious mansion filled with great wealth. Cut off with Arjuna's arrow, and deprived of life, the tall trunk of Karna endued with great splendour, with blood issuing from every wound, fell down like the thunder-riven summit of a mountain of red chalk with crimson streams running down its sides after a shower. Then from that body of the fallen Karna a light passing through the welkin penetrated the sun. This wonderful sight, O king, was beheld by the human warriors after the fall of Karna. Then the Pandavas, beholding Karna slain by Phalguna, loudly blew their conchs.
