Mahabharata Karna parva Chapter 90:6

Mahabharata Karna parva Chapter 90:6 Once more Arjuna pierced Karna in the centre of the chest with many straight-coursing and strong shafts made entirely of iron and equipped with wings of gold and each resembling the fiery rod of the Destroyer, like the son of Agni piercing the Krauncha mountains. Then the Suta's son, casting aside his bow that resembled the very bow of Sakra, as also his quiver, felt great pain, and stood inactive, stupefied, and reeling, his grasp loosened and himself in great anguish. The virtuous Arjuna, observant of the duty of manliness, wished not to slay his enemy while fallen into such distress. The younger brother of Indra then, with great excitement, addressed him, saying, "Why, O son of Pandu, dost thou become so forgetful? They that are truly wise never spare their foes, however weak, even for a moment. He that is learned earneth both merit and fame by slaying foes fallen into distress. Lose no time in precipitately crushing Karna who is always inimical to thee and who is the first of heroes. The Suta's son, when able, will once more advance against thee as before. Slay him, therefore, like Indra slaying the Asura Namuci." Saying, "So be it, O Krishna!" and worshipping Janardana, Arjuna, that foremost of all persons in Kuru's race once more quickly pierced Karna with many excellent arrows like the ruler of heaven, piercing the Asura, Samvara. The diadem-decked Partha, O Bharata, covered Karna and his car and steeds with many calf-toothed arrows, and putting forth all his vigour he shrouded all the points of the compass with shafts equipped with wings of gold. Pierced with those arrows equipped with heads like the calf's tooth, Adhiratha's son of broad chest looked resplendent like an Asoka or Palasa or Salmali decked with its flowery load or a mountain overgrown with a forest of sandal trees. Indeed, with those numerous arrows sticking to his body, Karna, O monarch, in that battle, looked resplendent like the prince of mountains with its top and glens overgrown with trees or decked with flowering Karnikaras. Karna also shooting repeated showers of arrows, looked, with those arrows constituting his rays, like the sun coursing towards the Asta hills, with disc bright with crimson rays. Shafts, however, of keen points, sped from Arjuna's arms, encountering in the welkin the blazing arrows, resembling mighty snakes, sped from the arms of Adhiratha's son, destroyed them all. Recovering his coolness, and shooting many shafts that resembled angry snakes, Karna then pierced Partha with ten shafts and Krishna with half a dozen, each of which looked like an angry snake. Then Dhananjaya desired to shoot a mighty and terrible arrow, made wholly of iron, resembling the poison of snake or fire in energy, and whose whizz resembling the peal of Indra's thunder, and which was inspired with the force of a high (celestial) weapon. At that time, when the hour of Karna's death had come, Kala, approaching invisibly, and alluding to the Brahmana's curse, and desirous of informing Karna that his death was near, told him, "The Earth is devouring thy wheel!" Indeed, O foremost of men, when the hour of Karna's death came, the high brahmastra that the illustrious Bhargava had imparted unto him, escaped from his memory.
