Matsya Purana — The Rite of Donating the ‘Mountain of Salt’
अनेन विधिना यस्तु दद्याल्लवणपर्वतम् उमालोके वसेत्कल्पं ततो याति परां गतिम् //
anena vidhinā yastu dadyāllavaṇaparvatam umāloke vasetkalpaṃ tato yāti parāṃ gatim //
Whoever, following this prescribed procedure, donates a “mountain of salt,” dwells for a kalpa in Umā’s world; thereafter, he attains the supreme state.
This verse does not discuss pralaya directly; it teaches dāna-phala (the spiritual result of a prescribed gift), linking ritual charity to long heavenly residence and ultimately the supreme goal.
It frames charitable giving (especially formally prescribed dānas) as a key householder/royal duty: performing the gift according to rule brings extraordinary merit, exemplary of dharmic governance and household piety.
The significance is ritual rather than architectural: the phrase “anena vidhinā” stresses correct procedure for a specific dāna—lavaṇa-parvata (a large, mountain-like heap of salt)—and promises a defined phala (reward).
