śrī-śukaḥ uvāca - Śrī Śukadeva Gosvāmī said; iti - thus; bruvāṇau - speaking; anyonyam - to one another; dharma-jijñāsayā - with a desire to know the supreme, ultimate religious principle (devotional service); nṛpa - O King; yuyudhāte - fought; mahā-vīryau - both very powerful; indra - King Indra; vṛtrau - and Vṛtrāsura; yudhām patī - both great military commanders.

Śrī Śukadeva Gosvāmī said: Vṛtrāsura and King Indra spoke about devotional service even on the battlefield, and then as a matter of duty they again began fighting. My dear King, both of them were great fighters and were equally powerful.
