Matsya Purana — Kailasa
दिव्यं च नन्दनं तत्र तस्यास्तीरे महद्वनम् प्रागुत्तरेण कैलासाद् दिव्यं सौगन्धिकं गिरिम् //
divyaṃ ca nandanaṃ tatra tasyāstīre mahadvanam prāguttareṇa kailāsād divyaṃ saugandhikaṃ girim //
There, too, is the celestial Nandana grove; upon its bank lies a vast forest. To the northeast of Mount Kailāsa stands the divine mountain called Saugaṇdhika.
This verse does not discuss Pralaya; it focuses on sacred geography—celestial groves and a divine mountain in the Himalayan region near Kailāsa.
Indirectly, it supports the Purāṇic ideal of dharmic living through pilgrimage and reverence for tīrthas—acts recommended for householders and patronized by kings to cultivate merit and social order.
No explicit Vāstu or temple rule appears here; the takeaway is ritual-topographical—identifying a sanctified landscape (Nandana grove, Kailāsa region) that functions as a setting for tīrtha-related rites and devotional observances.
