v1.c5.s2.113

With Vajra made of Dadhīci’s bones (made by Tvaṣṭr from sun’s tejas—Matsya P.), Indra attacked Vṛtra as Rudra attacked Yama. The encounter took place on the banks of the Narmadā in the first Tretāyuga. Battle described. Seeing his friends escaping in fright, Vṛtra encouraged them to stand and fight. He also disabled Indra’s Airāvata, and addressed him at length. Indra cut off one of his arms. With the remaining arm Vṛtra hit Indra while the Vajra slipped from his hands causing concern to the gods.
