This time Indra was more powerful, and he severed Vṛtrāsura’s remaining arm. Vṛtrāsura then assumed a gigantic form and swallowed King Indra, but Indra, being protected by the talisman known as Nārāyaṇa-kavaca, was able to protect himself even within Vṛtrāsura’s body. Thus he emerged from Vṛtrāsura’s abdomen and severed the demon’s head from his body with his powerful thunderbolt. Severing the demon’s head took one complete year to accomplish.
