Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
तद्यथा शीघ्रमेवैषां योगं यायात्पिनाकिना तथा विधेयं विधिवत् त्वया शैलेन्द्रसत्तम अत्यन्तं हि महत्कार्यं देवानां हिमभूधर //
tadyathā śīghramevaiṣāṃ yogaṃ yāyātpinākinā tathā vidheyaṃ vidhivat tvayā śailendrasattama atyantaṃ hi mahatkāryaṃ devānāṃ himabhūdhara //
Therefore, arrange matters so that their union with the Bearer of the Pināka (Śiva) may be accomplished swiftly. Do this properly, according to due procedure, O best of mountains—O snow-clad Himālaya—for this is indeed a supremely great undertaking for the gods.
This verse does not discuss Pralaya directly; it emphasizes a timely, divinely significant undertaking—ensuring a prescribed, orderly completion of a sacred union connected with the gods’ larger purpose.
By insisting on vidhivat (“according to due procedure”), it mirrors the Matsya Purana’s broader ethic: major social or religious acts—marriage alliances, rites, and state decisions—should be executed promptly yet strictly in accordance with dharma and proper ritual/legal norms.
The ritual significance lies in the stress on vidhivat—proper ordinance and correct method—an idea central to Purāṇic ritual culture (and, by extension, to Vastu/śilpa works where correct procedure governs successful outcomes).
