Mahabharata Drona Parva Chapter 175:2

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 175:2 A carnivorous and awful vulture of blood-red body perched on it. He came, forcibly drawing his bow whose twang resembled the thunder of Indra, and whose string was very hard, and which measured a dozen cubits in length and one cubit in breadth. Filling all the points of the compass with shafts of the measure of the Aksha of a car, the Rakshasa rushed against Karna on that night that was so destructive of heroes. Staying proudly on his car, as he stretched his bow, the twang that was heard resembled that sound of the roaring thunder. Frightened by him, O Bharata, all thy troops trembled like the surging waves of the ocean. Beholding that frightful Rakshasa of horrible eyes advancing against him, Radha's son, as if smiling, withstood him speedily. And Karna proceeded against the smiling Rakshasa, smiting him in return from a near point, like an elephant against an elephant or the leader of a bovine herd against the leader of another herd. The collision that took place between them, i.e., Karna and the Rakshasa, O king, became terrible and resembled that between Indra and Samvara. Each taking a formidable bow of loud twang, struck and covered the other with powerful shafts. With straight shafts sped from bows drawn to their fullest stretch, they mangled each other, piercing their coats of mail made of brass. With darts of the measure of Akshas, and shafts also they continued to mangle each other, like a couple of tigers or of mighty elephants with their teeth or tusks. Piercing each other's body, aiming shafts at each other, scorching each other with clouds of arrows, they became incapable of being gazed at. With limbs pierced and mangled with shafts, and bathed in streams of blood, they looked like two hills of chalk with rivulets running down their breasts. Those two mighty car-warriors, both struggling vigorously, both with limbs pierced with keen-pointed shafts, and each mangling the other, failed, however to make each other tremble. For a long time, that nocturnal combat between Karna and the Rakshasas in which both seemed to sport, making life itself the stake, continued equally. Aiming keen shafts and shooting them to the utmost measure of his might, the twang of Ghatotkacha's bow inspired both friends and foes with fear. At that time, O king, Karna could not prevail over Ghatotkacha. Seeing this, that foremost of all persons acquainted with weapons, invoked into existence celestial weapons. Beholding a celestial weapon aimed at him by Karna, Ghatotkacha, that foremost of Rakshasas invoked into existence his Rakshasa illusion. He was seen surrounded by a large force of terrible-looking Rakshasas, armed with lances, large rocks and hills and clubs. Beholding Ghatotkacha advancing with a mighty weapon uplifted (in his hands) like unto the Destroyer himself of all creatures armed with his fierce and fatal club, all the kings there were struck with fear. Terrified at the leonine roars uttered by Ghatotkacha, the elephants passed urine, and all the combatants trembled with fear.
