Matsya Purana — The Rite and Glory of Meru-Dāna: The Tenfold ‘Gift of Meru’ and Mountain-Offe...
शुक्लाम्बराण्यम्बुधरावली स्यात् पूर्वेण पीतानि च दक्षिणेन वासांसि पश्चादथ कर्बुराणि रक्तानि चैवोत्तरतो घनाली //
śuklāmbarāṇyambudharāvalī syāt pūrveṇa pītāni ca dakṣiṇena vāsāṃsi paścādatha karburāṇi raktāni caivottarato ghanālī //
In the east there should be a massing like a line of rain-clouds, with white garments; in the south, yellow garments; in the west, variegated garments; and in the north, red garments—thus is the prescribed arrangement.
It does not describe Pralaya directly; instead, it preserves a Vastu/ritual principle: harmony is maintained by aligning colors and arrangements with the cardinal directions, reflecting cosmic order rather than dissolution.
For a king commissioning temples or public rites—and for householders performing direction-based worship—this verse functions as a practical dharmic guideline: choose and place ritual garments/materials according to direction to ensure auspiciousness and social-religious order.
It assigns direction-wise color prescriptions (east-white, south-yellow, west-variegated, north-red) and hints at cloud-like massing/formation, useful for arranging participants, textiles, banners, or decorative elements in temple rituals and Vastu-aligned layouts.
