Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
दशाश्वमेधिकं पुण्यं गङ्गाद्वारं तथैव च नन्दाथ ललिता तद्वत् तीर्थं मायापुरी शुभा //
daśāśvamedhikaṃ puṇyaṃ gaṅgādvāraṃ tathaiva ca nandātha lalitā tadvat tīrthaṃ māyāpurī śubhā //
Daśāśvamedhika is a meritorious tirtha; so too is Gaṅgādvāra. Likewise, the tirthas Nandā and Lalitā are of the same kind; and the auspicious tirtha called Māyāpurī is also highly sacred.
This verse does not describe pralaya directly; it focuses on tirtha-mahātmyas—naming specific sacred sites whose visitation is said to generate puṇya (religious merit).
By highlighting recognized tirthas and their merit, the verse supports the householder/kingly duty of dharmic patronage and personal observance—undertaking pilgrimages, supporting sacred places, and cultivating puṇya through sanctioned religious practices.
The ritual significance is primary: these named locations are presented as tīrthas where acts like pilgrimage and sacred bathing are traditionally understood to yield spiritual merit; no specific Vāstu or temple-building rule is stated in this verse.
