Matsya Purana — Lineage of the Pitṛs
छागलाण्डे प्रचण्डा तु चण्डिका मकरन्दके सोमेश्वरे वरारोहा प्रभासे पुष्करावती //
chāgalāṇḍe pracaṇḍā tu caṇḍikā makarandake someśvare varārohā prabhāse puṣkarāvatī //
At Chāgalāṇḍa she is (known as) Pracaṇḍā; at Makarandaka she is Caṇḍikā; at Someśvara she is Varārohā; and at Prabhāsa she is Puṣkarāvatī.
This verse does not address Pralaya; it catalogues sacred places (tirthas) and the specific names by which the Goddess is worshipped in each locality.
Indirectly, it supports dharma through tirtha-yatra and Devi-upasana: a householder or king is encouraged (in Purāṇic practice) to honor regional forms of the Goddess, sponsor worship, and protect pilgrimage sites and temples.
The ritual takeaway is site-specific worship: the same Devi is invoked under different names at different tirthas, guiding correct mantra/name usage for offerings and temple liturgy at places like Someśvara and Prabhāsa.
