मुसलासिगदाहस्ता रथे चोष्णीषदंशिताः महामेघरवा नागा भीमोल्काशनिहेतयः //
musalāsigadāhastā rathe coṣṇīṣadaṃśitāḥ mahāmegharavā nāgā bhīmolkāśanihetayaḥ //
Armed with musalas, swords, and maces, and mounted on chariots with crested helmets fastened on, those Nāga warriors roared like great thunderclouds, wielding dreadful meteors and thunderbolts as their weapons.
This verse is not about Pralaya; it is a martial catalogue describing Nāga warriors’ arms, chariots, and thunder-like roar, using cosmic imagery (cloud, meteor, thunderbolt) to intensify battlefield power.
Indirectly, it reflects the kṣātra (royal/warrior) sphere emphasized in Purāṇic ethics: disciplined soldiery, proper armament, and organized chariot warfare—elements associated with a king’s duty to protect and wage righteous war when necessary.
No direct Vāstu or ritual instruction appears here; the key takeaway is iconographic-martial vocabulary (weapons, chariot, helmet/crest) useful for interpreting Purāṇic descriptions of warriors in temple reliefs and narrative art.
