Matsya Purana — The Rite of Donating the Golden Mountain
अनेन विधिना यस्तु दद्यात्कनकपर्वतम् स याति परमं ब्रह्मलोकमानन्दकारकम् तत्र कल्पशतं तिष्ठेत् ततो याति परां गतिम् //
anena vidhinā yastu dadyātkanakaparvatam sa yāti paramaṃ brahmalokamānandakārakam tatra kalpaśataṃ tiṣṭhet tato yāti parāṃ gatim //
Whoever, following this prescribed procedure, donates a “mountain of gold,” attains the supreme Brahma-world, the abode that bestows bliss. Having dwelt there for a hundred kalpas, he then proceeds to the highest final state.
It does not describe Pralaya directly; it uses Puranic cosmology (Brahmaloka and kalpa-time) to state the post-mortem fruit of a major charity, measured across vast cosmic cycles.
It frames dāna (charitable gifting) as a key householder/royal duty performed “by proper procedure,” promising elevated realms and ultimately the highest destiny—encouraging disciplined, rule-based generosity rather than mere display.
The focus is ritual: “anena vidhinā” implies a formally prescribed rite for offering a symbolic/constructed ‘golden mountain’ gift, emphasizing correct procedure (vidhi) in dāna rather than Vastu or temple construction.
