Matsya Purana — Procedure for Going to Prayaga and the Greatness of the Ganga
सागराः सरितः शैला नागा विद्याधराश्च ये हरिश्च भगवनास्ते प्रजापतिपुरःसरः //
sāgarāḥ saritaḥ śailā nāgā vidyādharāśca ye hariśca bhagavanāste prajāpatipuraḥsaraḥ //
Oceans, rivers, and mountains—together with the Nāgas and the Vidyādharas—and also Hari, the Blessed Lord: all these stand in attendance before Prajāpati, with him as their foremost head.
It presents a creation-era (cosmic order) tableau: natural powers (oceans, rivers, mountains) and supernatural races (Nāgas, Vidyādharas) are depicted as part of an ordered universe presided over by Prajāpati, with Hari also present—emphasizing hierarchy and governance rather than dissolution.
By portraying all realms—natural and celestial—as aligned under rightful leadership, the verse supports a key Purāṇic ethic: a king or householder should uphold order (dharma), harmonizing diverse constituents under a guiding principle, just as cosmic constituents stand in proper precedence before Prajāpati.
While not giving direct Vāstu rules, the verse provides a ritual-theological frame used in temple ideology: the cosmos is an ordered hierarchy with a presiding creator (Prajāpati) and Hari—mirrored in temple layouts where procession, precedence, and placement reflect cosmic order.
