Matsya Purana — The Terror of Tripura and the Gods’ Hymn to Śiva
ते यूयं यदि अन्ये च क्रतुविध्वंसकं हरम् याचामः सहिता देवं त्रिपुरं स हनिष्यति //
te yūyaṃ yadi anye ca kratuvidhvaṃsakaṃ haram yācāmaḥ sahitā devaṃ tripuraṃ sa haniṣyati //
If you and the others unite, let us beseech Hara—the destroyer of sacrifices; joined together, we shall petition that god, and he will slay Tripura.
This verse is not about cosmic dissolution (pralaya); it concerns a mythic crisis where the gods seek Śiva’s intervention to destroy Tripura.
Indirectly, it models dharmic strategy: when a threat exceeds one’s capacity, one should seek rightful divine/authoritative support and act in unity rather than in isolated rivalry.
Ritually, it highlights Śiva as “kratu-vidhvaṃsaka” (one who disrupts sacrifices), pointing to tensions between ritual power and higher divine authority; architecturally, “Tripura” implies fortified triple structures, but no Vāstu rule is specified in this verse.
