Surely even the wielder of the thunderbolt (Indra) himself cannot slay in battle by just means both Bhishma and Drona, while contending in battle. Indeed, that I tell you truly.
अश्रौषमहमेतद् वै भीष्मद्रोणौ निपातितौ। भीष्मद्रोणौ हि समरे न हन्याद् वज्रभृत् स्वयम्॥ न्यायेन युध्यमानौ हि तद् वै सत्यं ब्रवीमि ते।
