Matsya Purana — Kailasa
उद्गायता उदीच्यां तु अवगाढा महोदधिम् चक्रो बधिरकश्चैव तथा नारदपर्वतः //
udgāyatā udīcyāṃ tu avagāḍhā mahodadhim cakro badhirakaścaiva tathā nāradaparvataḥ //
In the northern quarter lies Udgāyatā; Avagāḍha is also there, reaching down to the great ocean. Likewise are Cakra and Badhiraka, and also the mountain known as Nārada.
This verse does not describe pralaya directly; it functions as a geographical catalogue of northern sacred places, using the phrase “great ocean” (mahodadhi) as a landmark rather than a flood narrative.
Indirectly, it supports the Purāṇic ideal of dharma through tīrtha-yātrā (pilgrimage): kings and householders are encouraged to know and honor sacred regions, supporting pilgrimage, temples, and the maintenance of holy sites.
Architectural rules are not stated here; the ritual takeaway is tīrtha-identification—these named sites (and Nārada mountain) are presented as recognized sacred locales for pilgrimage, worship, and merit-accruing observances.
