Matsya Purana — Description of Gomedaka and Puṣkara Dvīpas; the Lokāloka Boundary; Ocean Tide...
गोपायन्ते प्रजास्तत्र सर्वैः सहजपण्डितैः भोजनं चाप्रयत्नेन सदा स्वयमुपस्थितम् //
gopāyante prajāstatra sarvaiḥ sahajapaṇḍitaiḥ bhojanaṃ cāprayatnena sadā svayamupasthitam //
There, all people are safeguarded by those wise by nature; and food is ever at hand without exertion, as though it appears of its own accord.
This verse is not about Pralaya; it describes an ideal, stable social order where protection and sustenance are naturally ensured through righteous governance and innate wisdom.
It reflects Rajadharma: a ruler’s foremost duty is the protection (gopālana) of subjects and the establishment of conditions where basic needs—especially food—are easily met; it also implies that society should be guided by the naturally wise, not merely the powerful.
No explicit Vāstu or ritual procedure is stated; the significance is indirect—prosperity and “food appearing without effort” is a hallmark of dharmic order, which elsewhere supports temple-building, charity, and yajña as sustainable civic life.
