"Drona said, 'The foe, O sire, I see not who may slay me while standing in battle I am engaged in fight, with wrath excited, and scattering (my) arrowy showers continually. Except when addrest for death O king, having abandoned my arms and withdrawn (in Yoga meditation) from surrounding sights, none will be able to slay me. This that I tell thee is true. I also tell thee truly that I will cast off my arms in battle, having heard something very disagreeable from some one of credible speech.--'"
