Stay thou: I will shoot at thee shafts like thunderbolts. Strive thou also and shoot, to the best of thy power, thy arrows at me.' Hearing these words of the Kirata, Arjuna became angry, and attacked him with arrows. The Kirata, however, with a glad heart received all those shafts upon himself, repeatedly saying, 'Wretch, wretch, shoot thou best arrows capable of piercing into the very vitals.' Thus addressed, Arjuna, began to shower his arrows on him. Both of them then became angry and, engaging in fierce conflict, began to shoot at each other showers of arrows, each resembling a snake of virulent poison. And Arjuna rained a perfect shower of arrows on the Kirata, Sankara, however, bore that downpour on him with a cheerful heart. But the wielder of the Pinaka, having borne that shower of arrows for a moment, stood unwounded, immovable like a hill. Dhananjaya, beholding his arrowy shower become futile, wondered exceedingly, repeatedly saying, 'Excellent! Excellent! Alas, this mountaineer of delicate limbs, dwelling on the heights of the Himavat, beareth, without wavering, the shafts shot from the Gandiva! Who is he? Is he Rudra himself, or some other god, or a Yaksha, or an Asura? The gods sometimes do descend on the heights of the Himavat. Except the god who wieldeth the Pinaka, there is none rise that can bear the impetuosity of the thousands of arrows shot by me from the Gandiva.
