Matsya Purana — Kailasa
तस्यास्तीरे वनं दिव्यं महच्चैत्ररथं शुभम् तस्मिन्गिरौ निवसति मणिभद्रः सहानुगः //
tasyāstīre vanaṃ divyaṃ mahaccaitrarathaṃ śubham tasmingirau nivasati maṇibhadraḥ sahānugaḥ //
On its bank lies a divine forest—vast, auspicious, and famed as Caitraratha. Upon that mountain dwells Maṇibhadra, attended by his retinue.
This verse does not discuss Pralaya; it highlights sacred geography—an auspicious divine forest and a supernatural guardian figure (Maṇibhadra) residing there.
Indirectly, it supports the Purāṇic ideal that rulers and householders should honor tīrthas and sacred sites—places protected by divine or semi-divine beings—through pilgrimage, restraint, and offerings, thereby cultivating dharma and public sanctity.
Architectural rules are not stated, but the verse functions as a tīrtha-marker: identifying a sanctified landscape (forest-bank-mountain) that would traditionally warrant ritual visitation, worship of local guardians, and establishment of regulated sacred space.
