Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
स हि धर्मरथः श्रीमांस् तेन विष्णुपदे गिरौ सोमः शुक्रेण वै राज्ञा सह पीतो महात्मना //
sa hi dharmarathaḥ śrīmāṃs tena viṣṇupade girau somaḥ śukreṇa vai rājñā saha pīto mahātmanā //
For he was the illustrious king Dharmaratha; on that Vishnupada Mountain, Soma (the Moon) was indeed drunk together with Śukra by that great-souled ruler.
This verse does not describe Pralaya; it highlights tirtha-mahātmya—how a sacred place (Vishnupada-giri) is linked with extraordinary, merit-bearing events involving divine powers.
By presenting Dharmaratha as “śrīmān” and “mahātman,” the verse frames righteous kingship as aligned with pilgrimage and dharma—seeking sanctification through holy sites and upholding religious merit as part of royal conduct.
The ritual cue is the sacred-site setting (Vishnupada on a mountain), implying tirtha observances and offerings; no direct Vāstu/temple-measurement rule is stated in this verse.
