Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
अहन्यहनि देवेन्द्रं द्रष्टुं याति स राजराट् कदाचिदारुह्य रथं दक्षिणाम्बरचारिणम् //
ahanyahani devendraṃ draṣṭuṃ yāti sa rājarāṭ kadācidāruhya rathaṃ dakṣiṇāmbaracāriṇam //
Day after day that sovereign king went to behold Devendra (Indra); and once, mounting a chariot, he set out along the southern course, toward the southern quarter.
This verse does not discuss Pralaya directly; it highlights a royal pattern of repeatedly seeking Indra’s audience, suggesting a governance model grounded in divine consultation rather than cosmological dissolution.
It depicts the king’s disciplined, regular approach to receiving guidance from Devendra—an ethical Rajadharma ideal where a ruler seeks higher counsel, acts with restraint, and aligns decisions with dharma rather than mere personal will.
No explicit Vāstu or temple-ritual rule is stated; however, the mention of moving toward the southern quarter (dakṣiṇā) can be read as directional awareness, a theme that later becomes technically important in Vāstu and ritual orientation.
