Matsya Purana — Vishnu’s Names Across Yugas and the Gods’ Refuge During the Tārakāmaya War
प्रवृत्तधर्माः संवृत्ता लोका मुदितमानसाः विष्णोर्दत्तप्रतिज्ञस्य श्रुत्वारिनिधने गिरम् //
pravṛttadharmāḥ saṃvṛttā lokā muditamānasāḥ viṣṇordattapratijñasya śrutvārinidhane giram //
When they heard the deathless, enemy-destroying utterance of Viṣṇu—who had given his pledged assurance—the worlds became well-ordered again: dharma resumed its course, and people’s hearts were filled with joy.
It highlights the post-pralaya restoration: once Viṣṇu’s imperishable assurance is heard, dharma restarts and the worlds return to stable order.
By stressing “dharma set in motion again,” it implies that social and royal duties resume after crisis—stability and right conduct depend on keeping faith with vows and upholding dharma.
No direct Vāstu or ritual rule is stated; the takeaway is thematic—ritual and societal order are meaningful only when dharma is re-established under divine protection.
