Matsya Purana — The Battle at Tripura: Shiva’s Strategy
ततो ऽसुरवरः श्रीमांस् तारकाख्यः प्रतापवान् सतरूणां गिरीणां वै तुल्यरूपधरो बभौ //
tato 'suravaraḥ śrīmāṃs tārakākhyaḥ pratāpavān satarūṇāṃ girīṇāṃ vai tulyarūpadharo babhau //
Then that illustrious and mighty lord of the Asuras, named Tāraka, appeared—assuming a form comparable to the lofty mountains, like Satarūṇa in grandeur and aspect.
This verse is not about Pralaya; it focuses on the manifestation and formidable, mountain-like grandeur of the Asura Tāraka within a Deva–Asura narrative.
Indirectly, it frames the ethical-political backdrop common in Purāṇas: when destructive power rises (symbolized by Tāraka’s overwhelming might), kingship and dharma are tested—prompting protection of order, subjects, and ritual life.
No direct Vāstu or ritual procedure is stated; the verse uses mountain-comparison imagery (giri) to convey scale and majesty, a stylistic device also seen in iconographic descriptions but not a technical rule here.
