"Vaisampayana continued, 'Hearing these words of Arjuna, Uttara cast off all inactivity. And he speedily alighted from the tree, bringing with him Arjuna's weapons. Then Arjuna addressed him, saying, 'Yes, I will fight with the Kurus and recover thy kine. Protected by me, the top of this car will be to thee as a citadel. The passages and alleys and other divisions of this car will be the streets and edifices of that fortified city. These my arms will be its ramparts and gateways. This treble pole and my quiver will constitute defensive works inaccessible to the foe. This my banner--single and grand--will it not alone be equal unto those of thy city? This my bow-string will constitute the catapults and cannons for vomiting forth missiles on the besiezing ghost. My excited wrath will make that fortress formidable, and the clatter of my car-wheels--will it not resemble the kettle-drums of thy capital? Ridden by myself wielding the Gandiva, this car will be incapable of being vanquished by the hostile host, O son of Virata, let thy fear be dispelled.'
