Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
भद्रतीर्थं च विख्यातं पम्पातीर्थं च शाश्वतम् पुण्यं रामेश्वरं तद्वद् एलापुरमलं पुरम् //
bhadratīrthaṃ ca vikhyātaṃ pampātīrthaṃ ca śāśvatam puṇyaṃ rāmeśvaraṃ tadvad elāpuramalaṃ puram //
Also famed are Bhadratīrtha and the eternal Pampā-tīrtha; likewise the holy Rāmeśvara, and the spotless city of Elāpura.
This verse does not describe pralaya; it functions as a tīrtha-mahātmya style catalogue, emphasizing places whose sanctity is considered enduring (śāśvata) and merit-giving (puṇya).
By naming merit-conferring pilgrimage sites, the verse supports the dharmic ideal that householders and rulers should periodically undertake tīrtha-yātrā, sponsor pilgrim welfare, and cultivate puṇya through sacred travel, bathing, and worship.
The ritual significance is primary: these are tīrthas associated with purification and puṇya (especially Pampā-tīrtha and Rāmeśvara). While no explicit Vāstu rule is stated, such verses guide where temples, bathing ghāṭs, and pilgrimage infrastructure are traditionally established.
