Matsya Purana — The Greatness of Prayaga and the Supremacy of Cow-Donation
सर्वकामफला वृक्षा मही यत्र हिरण्मयी ऋषयो मुनयः सिद्धास् तत्र लोके स गच्छति //
sarvakāmaphalā vṛkṣā mahī yatra hiraṇmayī ṛṣayo munayaḥ siddhās tatra loke sa gacchati //
He goes to that world where the trees bear the fruits of every desire, where the earth is golden, and where Ṛṣis, Munis, and perfected Siddhas dwell.
It does not describe Pralaya directly; it depicts a merit-born higher realm (loka) characterized by abundance and the presence of perfected beings.
It frames ethical living and meritorious action as leading to elevated states of existence—an incentive for kings and householders to uphold dharma, charity, and disciplined conduct.
No explicit Vāstu or ritual procedure is stated; the imagery functions as a theological description of a perfected realm rather than a temple-building or rite manual.
