Mbh 7.134.1b

Who is there among the Asuras that would venture to stay before the great Indra with the thunderbolt uplifted in his hand?[157] A man may return having entered the abode of the dead, but none, however, can return having encountered Bhimasena! Those men of weak prowess, who senselessly rushed against the angry Bhimasena were like insects falling upon a blazing fire. Without doubt, reflecting upon what the angry and fierce Bhima had said in the assembly in the hearing of the Kurus about the slaughter of my sons, and beholding the defeat of Karna, Duhsasana and his brothers ceased to encounter Bhima from fear. That wicked son also of mine, O Sanjaya, who repeatedly said in the assembly (these words, viz.,) “Karna and Duhsasana and I myself will vanquish the Pandavas in battle,”--without doubt, beholding Karna defeated and deprived of his car by Bhima, is consumed with grief in consequence of his rejection of Krishna’s suit![158] Beholding his mail-clad brothers slain in battle by Bhimasena, in consequence of his own fault, without doubt, my son is burning with grief. Who that is desirous of life will make a hostile advance against Pandu’s son, Bhima, excited with wrath armed with terrible weapons and standing in battle like Death himself? A man may escape from the very jaws of the Vadava fire. But it is my belief that no one can escape from before Bhima’s face. Indeed, neither Partha, nor the Panchalas, nor Kesava, nor Satyaki, when excited with wrath in battle, shows the least regard for (his) life. Alas, O Suta, the very lives of my sons are in danger.’
