माघे निश्यार्द्रवासाः स्यात् सप्तम्यां गोप्रदो भवेत् दिवि कल्पमुषित्वेह राजा स्यात्पवनं व्रतम् //
māghe niśyārdravāsāḥ syāt saptamyāṃ goprado bhavet divi kalpamuṣitveha rājā syātpavanaṃ vratam //
মাঘ মাহত ৰাতিৰ শিশিৰে সিক্ত বস্ত্ৰ পৰিধান কৰিব লাগে। সপ্তমী তিথিত গোদান কৰা উচিত। স্বৰ্গত এক কল্পকাল বাস কৰি পাছত ইয়াত ৰজা হয়; ইয়াক পৱন-ব্ৰত বোলা হয়।
This verse is not about pralaya; it belongs to vrata-phalāni (results of vows), describing a Māgha observance and its karmic fruit (heavenly enjoyment and later kingship).
It prescribes householder-style dharma: bodily discipline (austerity through dew-damp clothing) and charity (go-dāna on Saptamī), teaching that purity and generosity are foundations for prosperity and rulership.
The significance is ritual rather than architectural: it defines a specific tithi-based observance in Māgha, culminating in cow-gift charity, and names the practice as the Pavana (purifying) vrata.
