Matsya Purana — The Burning of Tripura and Rudra’s Victory
शूलनिर्दारितोरस्का गदाचूर्णितमस्तकाः इषुभिर्गाढविद्धाश्च पतन्ति प्रमथार्णवे //
śūlanirdāritoraskā gadācūrṇitamastakāḥ iṣubhirgāḍhaviddhāśca patanti pramathārṇave //
Their chests split open by tridents, their heads crushed by maces, and pierced deep by arrows, they fall into the ocean-like mass of the Pramathas (the tumultuous host).
It does not teach cosmic Pralaya directly; it uses an “ocean” metaphor (arṇava) to depict the vastness and turbulence of the Pramatha host during battle.
Indirectly, it reflects the Purāṇic ethic that violence belongs to the battlefield context of protecting order; it is not a household injunction, but a narrative illustration of the consequences of armed conflict.
No Vāstu/temple-building rule is stated here; the verse is purely martial imagery (trident, mace, arrows) within a mythic combat description.
