Matsya Purana — The Battle at Tripura: Shiva’s Strategy
प्राकारगोपुराट्टेषु कक्षान्ते दानवाः स्थिताः इमे च तोयदाभासा दनुजा विकृताननाः //
prākāragopurāṭṭeṣu kakṣānte dānavāḥ sthitāḥ ime ca toyadābhāsā danujā vikṛtānanāḥ //
Upon the ramparts and at the gate-towers, and at the edge of the inner enclosure, the Dānavas were stationed—these sons of Danu, cloud-dark in appearance, with distorted and fearsome faces.
This verse does not describe Pralaya; it depicts a tactical placement of Dānavas at ramparts, gate-towers, and enclosure edges, emphasizing threat and vigilance rather than cosmic dissolution.
It supports the king’s duty of protection (rakṣaṇa): maintaining guarded walls, gates, and inner wards, and anticipating hostile forces at key defensive points of a settlement.
Architecturally, it highlights fort components central to Vāstu-based defense—prākāra (rampart), gopura (gate-tower), and kakṣā (enclosed ward)—showing the strategic importance of layered enclosures and guarded gateways.
