I will slay thee. Wait for a moment without flying away.” Saying thus, Dhrishtadyumna of great prowess struck the preceptor’s son with many keen and terrible arrows capable of piercing the very vitals. Those swiftly-coursing shafts, equipped with golden wings and keen points, and capable of piercing the body of every foe proceeding in a continuous line, penetrated into Aswatthaman’s body, like freely-roaming bees in search of honey entering a flowering tree. Deeply pierced and swelling with rage, like a trodden snake, the proud and fearless son of Drona, arrow in hand, addressed his foe, saying, “O Dhrishtadyumna, wait for moment, without leaving my presence.

O thou of wicked understanding, having first slain Drona himself, I will not, therefore, slay thee today when Drona himself is still alive. O thou of wicked understanding, after this night passeth away and bringeth in the fair dawn, I shall first slay thy sire in battle and then despatch thee also to the region of Spirits. Even this is the wish entertained by me. Standing before me, display, therefore, till then, the hatred thou bearest towards the Parthas, and the devotion thou cherishest for the Kurus. Thou shalt not escape from me with life.
