Matsya Purana — Agastya’s Origin
विन्ध्यवृद्धिक्षयकर मेघतोयविषापह रत्नवल्लभ देवेश लङ्कावासिन्नमो ऽस्तु ते //
vindhyavṛddhikṣayakara meghatoyaviṣāpaha ratnavallabha deveśa laṅkāvāsinnamo 'stu te //
O Lord who can cause the Vindhya to wax or wane, remover of the poison in rain-water, beloved of jewels, Lord of the gods, Dweller in Laṅkā—salutations be to You.
It does not describe Pralaya directly; instead, it praises divine sovereignty over natural processes—growth and decline of mountains and the purification of waters—powers that, in Purāṇic thought, also underlie cosmic maintenance.
The verse models daily dharmic conduct through reverent praise (stuti) and recognition of divine guardianship over public welfare resources like water; for householders and kings alike, honoring the divine and protecting clean water are implied ethical duties.
Ritually, it functions as a protective invocation (namas) emphasizing purification of water—relevant to temple and domestic rites where uncontaminated water is essential for abhiṣeka, ācamana, and consecrations.
