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.[232] 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.[233] 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. Then there fell on all sides a thick rain of rocks and stones poured incessantly by the Rakshasas, who had, in consequence of midnight, became inspired with greater strength.[234] Iron wheels and Bhusundis, and darts, and lances and spears and Sataghnis and axes also began to fall incessantly. Beholding that fierce and terrible battle, all the kings, as also thy sons and the combatants, fled away in fear. Only one amongst them, viz., Karna, proud of the power of his weapons, and feeling a noble pride, trembled not.
