Mbh 11.12.1b

Having embraced Yudhishthira the just and spoken a few words of comfort to him, O Bharata, the wicked-souled Dhritarashtra sought for Bhima, like a blazing fire ready to burn everything that would approach it. Indeed, that fire of his wrath, fanned by the wind of his grief, seemed then to be ready to consume the Bhima-forest. Ascertaining the evil intentions cherished by him towards Bhima, Krishna, dragging away the real Bhima, presented an iron statue of the second son of Pandu to the old king. Possessed of great intelligence, Krishna had, at the very outset, understood the intentions of Dhritarashtra, and had, therefore, kept such a contrivance ready for baffling them. Seizing with his two arms that iron Bhima, king Dhritarashtra, possessed of great strength, broke into pieces, thinking it to be Bhima himself in flesh and blood. Endued with might equal to that of 10,000 elephants, the king reduced that statue into fragments. His own breast, however, became considerably bruised and he began to vomit blood. Covered with blood, the king fell down on the ground like a parijata tree topped with its flowery burden. His learned charioteer Sanjaya, the son of Gavalgana, raised the monarch and soothing and comforting him, said, 'Do not act so.' The king then, having cast off his wrath and returned to his normal disposition, became filled with grief and began to weep aloud, saying, 'Alas, oh Bhima, alas, oh Bhima!' Understanding that he was no longer under the influence of wrath, and that he was truly sorry for having (as he believed) killed Bhima, Vasudeva, that foremost of men, said these words, 'Do not grieve, O Dhritarashtra, for thou hast not slain Bhimasena! That is an iron statue, O king, which has been broken by thee! Understanding that thou wert filled with rage, O bull of Bharata's race, I dragged the son of Kunti away from within the jaws of Death. O tiger among kings, there is none equal to thee in strength of body.
