Immensely fortunate are the kshatriyas (warring community), who get the opportunity to fight a war of this kind, which chance has brought, opening the gates to heaven.
Krishna reminds Arjuna that Arjuna did not love or seek the war at all. Duryodhana’s enmity towards Pandavas began right from his childhood.
At the time the kingdom was partitioned, King Dhritarashtra had driven them off to the barren land of Indraprastha. There Pandavas strove hard and prospered. Seeing the fortune during Yudhishthira’s Rajasooya Y¡ga, Duryodhana became sleepless. Shakuni, his uncle, prompted him to invite Yudhishthira for dice play, cheated him by foul means, and sent Pandavas for a long forest exile followed by a risky incognito life.
On Pandavas’ return, Duryodhana did not part with their kingdom, saying “fight and get it”.
Thus the war has come unsought, by chance. Only fortunate kshatriyas will have such a grace. It is undoubtedly an open door to heaven, the place for the virtuous, points Krishna.
