Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
हरिर् हरिद्भिर् ह्रियते तुरंगमैः पिबत्यथापो हरिभिः सहस्रधा पुनः प्रमुञ्चत्यथ ताश्च यो हरिः स मुह्यमानो हरिभिस्तुरंगमैः //
harir haridbhir hriyate turaṃgamaiḥ pibatyathāpo haribhiḥ sahasradhā punaḥ pramuñcatyatha tāśca yo hariḥ sa muhyamāno haribhisturaṃgamaiḥ //
Hari is carried by tawny horses; then, by those same tawny ones, he drinks up the waters in a thousand streams, and again releases them. That Hari—bewildered amid those tawny horses—thus appears in this ceaseless taking and letting-go.
It presents pralaya as a cyclical divine action: the waters are absorbed and released again, implying dissolution and re-manifestation under Hari’s governance.
Indirectly, it teaches steadiness amid upheaval: just as cosmic order moves through taking and releasing, a ruler or householder should act without confusion during crises, maintaining dharma through cycles of loss and restoration.
No direct Vastu/ritual rule appears; the verse is primarily cosmological and symbolic, useful in ritual reading as a meditation on Vishnu’s control over the waters and cosmic cycles.
