Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
एता मध्यास्तथान्याश्च ह्लादिन्यो हिमसर्जनाः शुक्लाश्च ककुभश्चैव गावो विश्वसृतश्च याः //
etā madhyāstathānyāśca hlādinyo himasarjanāḥ śuklāśca kakubhaścaiva gāvo viśvasṛtaśca yāḥ //
These are the intermediate rays, and there are others as well: those that are delight-giving, those that produce snow, the white ones; and likewise the directional quarters (kakubhas), and the “cows” said to pervade and flow forth into the whole world.
This verse is not directly about Pralaya; it functions as a classificatory list describing types/groups linked with directions and qualities (cooling, snow-producing, whiteness), supporting an ordered cosmology rather than dissolution.
By emphasizing ordered categories like the quarters (kakubhas), it supports the Dharma of maintaining right orientation in settlements, rituals, and construction—practical concerns for householders and rulers responsible for planning and public works.
The explicit mention of kakubhas (directions) points to Vastu-based orientation: ritual spaces and buildings are aligned by quarters, and qualities associated with directions guide placement and auspicious layout.
