Matsya Purana — The Battle at Tripura: Shiva’s Strategy
तारकाख्यपुरे दैत्यास् तारकाख्यपुरःसराः निर्गताः कुपितास्तूर्णं बिलादिव महोरगाः //
tārakākhyapure daityās tārakākhyapuraḥsarāḥ nirgatāḥ kupitāstūrṇaṃ bilādiva mahoragāḥ //
In the city called Tārakākhya, the Daityas—led by the foremost of that very city—burst forth in anger, swiftly, like great serpents emerging from their holes.
This verse does not describe Pralaya; it depicts a sudden, forceful emergence of Daityas from a city, using a vivid simile (serpents from burrows) to convey rapid mobilization.
Indirectly, it underscores the political reality of threats arising from within or near cities—implying the king’s duty to maintain vigilance, intelligence, and timely defense when hostile forces surge forth.
Architecturally, the imagery of beings emerging from 'bilas' (holes/burrows) echoes motifs relevant to fortified spaces and hidden passages; in a Vastu/town-planning reading, it highlights the importance of secure city design against sudden incursions.
