Matsya Purana — Description of Gomedaka and Puṣkara Dvīpas; the Lokāloka Boundary; Ocean Tide...
उदयात्पयसां योगात् पुष्पन्त्य् आपो यथा स्वयम् तथा स तु समुद्रो ऽपि वर्धते शशिनोदये //
udayātpayasāṃ yogāt puṣpanty āpo yathā svayam tathā sa tu samudro 'pi vardhate śaśinodaye //
Just as waters, by their own nature, seem to “blossom” (swell and rise) through conjunction with a milky essence at its rising, so too the ocean itself increases when the Moon rises.
It does not directly describe Pralaya; it highlights a recurring cosmic rhythm—lunar rise correlating with the swelling of waters—often used in Purāṇic literature to illustrate how nature follows higher cosmic order.
Indirectly, it supports dharmic governance and household planning by encouraging attention to natural cycles (lunar timing and water behavior), which affects travel, coastal safety, agriculture, and ritual scheduling.
Architecturally, it implies practical awareness of water rise near coasts and river mouths; ritually, it aligns with choosing lunar timings (śaśinodaya-related observances) when water levels and purity practices are considered significant.
