Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
नकुलेशस्य तीर्थं च कर्दमालं तथैव च दिण्डिपुण्यकरं तद्वत् पुण्डरीकपुरं तथा //
nakuleśasya tīrthaṃ ca kardamālaṃ tathaiva ca diṇḍipuṇyakaraṃ tadvat puṇḍarīkapuraṃ tathā //
And there is the sacred ford of Nakuleśa; likewise Kardamāla; and in the same way Diṇḍi, bestowing religious merit; and also Puṇḍarīkapura.
This verse does not address Pralaya; it is a catalog-style listing of tirthas (pilgrimage places) considered punya-generating within the Matsya Purana’s sacred geography section.
It supports dharmic practice through tirtha-yatra: householders (and kings as patrons) are encouraged to honor and visit merit-giving sacred sites, reinforcing public religion, charity, and the maintenance of holy places.
The ritual significance is the identification of specific locations as punya-karaka (merit-bestowing) tirthas; such verses commonly underpin later practices like establishing shrines, performing snana (sacred bathing), and endowing temples at these named kshetras.
