On earth they appear to men as two different persons, though ir reality they are of one and the same soul. That highly-renowned invincible pair, can with the fiat of their will slay this host, if only they wish it. But for humanity's sake, they do not wish it. O son, the slaughter of Bhishma and Drona, of high souls, appears to be like the over-turning of the Yuga and the stupefaction of the senses. In this world neither by Brahmacharya, nor by the study of the Vedas.
