And then the Kuru prince, with the whole might of his arms, struck that sharp weapon upon the head of the Kirata, a weapon that was incapable of being resisted even by solid rocks. But that first of swords, at touch of the Kirata's crown, broke into pieces. Phalguna then commenced the conflict with trees and stones. The illustrious god in the form of the huge-bodied Kirata, however, bore that shower of trees and rocks with patience. The mighty son of Pritha then, his mouth smoking with wrath, struck the invincible god in the form of a Kirata, with hi clenched fists, blows that descended like thunderbolts. The god in the Kirata form returned Phalguna's blows with fierce blows resembling the thunderbolts of Indra. And in consequence of that conflict of blows between the son of Pandu and the Kirata, there arose in that place loud and frightful sounds. That terrible conflict of blows, resembling the conflict of yore between Vritra and Vasava, lasted but for a moment. The mighty Jishnu clasping the Kirata began to press him with his breast, but the Kirata, possessed of great strength pressed the insensible son of Pandu with force. And in consequence of the pressure of their arms and of their breasts, their bodies began to emit smoke like charcoal in fire. The great god then, smiting the already smitten son of Pandu, and attacking him in anger with his full might, deprived him of his senses.
