Mbh 12.98.6c

The sages have said that that warrior who regards the van of the hostile army as the chambers of his wives, who looks upon the van of his own army as the vessel for the keep of sacrificial offering, who takes the combatants standing to his south for his Sadasyas and those to his north as his Agnidhras, and who looks upon the hostile forces as his wedded wife, succeeds in winning all regions of felicity.[292] The open space lying between two hosts drawn up for fight constitutes the altar of such a sacrificer, and the three Vedas are his three sacrificial fires. Upon that altar, aided by the recollection of the Vedas, he performs his sacrifice. The inglorious warrior who, turning away from the fight in fear, is slain by foes, sinks into hell. There is no doubt in this. That warrior, on the other hand, whose blood drenches the sacrificial altar already strewn with hair and flesh and bones, certainly succeeds in attaining a high end. That powerful warrior who, having slain the commander of the hostile army, mounts the vehicle of his fallen antagonist, comes to be regarded as possessed of the prowess of Vishnu himself and the intelligence of Vrihaspati, the preceptor of the celestials. That warrior who can seize alive the commander of the hostile army or his son or some other respected leader, succeeds in winning regions of felicity like mine. One should never grieve for a hero slain in battle. A slain hero, if nobody grieves for him, goes to heaven and earns the respect of its denizens. Men do not desire to dedicate (for his salvation) food and drink. Nor do they bathe (after receiving the intelligence), nor go into mourning for him. Listen to me as I enumerate the felicity that is in store for such a person. Foremost of Apsaras, numbering by thousands, go out with great speed (for receiving the spirit of the slain hero) coveting him for their lord. That Kshatriya who duly observes his duty in battle, acquires by that act the merit of penances and of righteousness.
