Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
*ब्रह्मोवाच विभावरि महत्कायं विबुधानामुपस्थितम् तत्कर्तव्यं त्वया देवि शृणु कार्यस्य निश्चयम् //
*brahmovāca vibhāvari mahatkāyaṃ vibudhānāmupasthitam tatkartavyaṃ tvayā devi śṛṇu kāryasya niścayam //
Brahmā said: “O Vibhāvarī, a mighty host of the gods has assembled. Therefore, O goddess, listen—this is what must be done by you; hear the settled decision regarding the task.”
It does not directly describe Pralaya; it shows a governance moment where Brahmā convenes or responds to an assembled body of devas and issues a decisive instruction—typical of cosmic administration before or during major events.
The verse models dharmic procedure: when a serious matter arises and elders/authorities assemble, one should hear the determined course of action and carry out one’s assigned duty without hesitation—an administrative ethic applicable to rulers and householders.
No explicit Vāstu or ritual rule is stated; the key takeaway is procedural—authoritative instruction (niścaya) is announced in an assembly setting, a pattern often used in the Purāṇa before prescribing rites or technical regulations elsewhere.
