Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
तद्यथा शैलजा देवी योगं यायात्पिनाकिना शीघ्रं तदुद्यमः सर्वैर् अस्मत्पक्षैर्विधीयताम् //
tadyathā śailajā devī yogaṃ yāyātpinākinā śīghraṃ tadudyamaḥ sarvair asmatpakṣairvidhīyatām //
Therefore, let us act swiftly so that the Mountain-born Goddess (Pārvatī) may enter into yogic union with Pinākin (Śiva, bearer of the bow); let this effort be undertaken at once by all those on our side.
This verse does not address pralaya; it focuses on divine initiative to facilitate the union of Pārvatī with Śiva.
Indirectly, it models decisive, coordinated action toward a dharmic objective—suggesting that leaders should act promptly and collectively to support socially and spiritually auspicious unions and outcomes.
No explicit Vāstu or temple-ritual rule appears here; the key term is 'yoga' in the sense of sacred union, which can be ritually framed in broader Purāṇic contexts but is not specified in this verse.
