The protective armor of Nārāyaṇa, which Indra possessed, was identical with Nārāyaṇa Himself, the Supreme Personality of Godhead. Protected by that armor and by his own mystic power, King Indra, although swallowed by Vṛtrāsura, did not die within the demon’s belly.

Но Индра был облачен в броню из мантры, «Нараяна-кавачу», которая неотлична от Самого Господа. Защищенный ею и своей чудесной силой, царь Индра не погиб во чреве Вритрасуры.
