Matsya Purana — Division of Bhārata-varṣa
सप्त चास्मिन्महावर्षे विश्रुताः कुलपर्वताः महेन्द्रो मलयः सह्यः शुक्तिमानृक्षवानपि //
sapta cāsminmahāvarṣe viśrutāḥ kulaparvatāḥ mahendro malayaḥ sahyaḥ śuktimānṛkṣavānapi //
In this great region (Bhārata-varṣa) there are seven renowned ‘kulaparvatas’ (chief mountain ranges): Mahendra, Malaya, Sahya, Śuktimān, and also Ṛkṣavān.
This verse is not about Pralaya; it belongs to the Matsya Purana’s cosmographic mapping of Bhārata-varṣa, listing major mountain ranges that structure the land.
Indirectly, it supports dharmic governance and household life by defining the sacred geography of the realm—knowledge used for administering regions, recognizing tīrthas, and situating rituals and pilgrimages within Bhārata-varṣa.
No direct Vāstu rule is stated, but such geographic catalogues inform temple–tīrtha networks and pilgrimage planning; in Purāṇic practice, mountains are treated as sacred anchors for rites and regional sanctuaries.
