Matsya Purana — The Burning of Tripura and Rudra’s Victory
रमणैरुपगूढाश्च रमन्त्यो रमणैः सह दह्यन्ते दानवेन्द्राणाम् अग्निना ह्यपि ताः स्त्रियः //
ramaṇairupagūḍhāśca ramantyo ramaṇaiḥ saha dahyante dānavendrāṇām agninā hyapi tāḥ striyaḥ //
Even those women—embraced by their lovers and sporting together with them—were burned by the fire of the Dānava-lords as well.
It uses pralaya-like imagery—inescapable, consuming fire—to depict total destruction, emphasizing that worldly attachment offers no refuge when a catastrophic end arrives.
By showing pleasure and intimacy overwhelmed by sudden ruin, it implicitly warns rulers and householders to uphold dharma and restraint, not relying on enjoyment or power as protection against the consequences of adharma and fate.
No direct Vāstu/temple or ritual procedure is stated; the key takeaway is symbolic—fire as a purifying/ending force—often echoed in Purāṇic ritual imagination, but not as a technical Vāstu rule in this verse.
