Matsya Purana — Lineage of the Pitṛs
सह्याद्राव् एकवीरा तु हरिश्चन्द्रे तु चन्द्रिका रमणा रामतीर्थे तु यमुनायां मृगावती //
sahyādrāv ekavīrā tu hariścandre tu candrikā ramaṇā rāmatīrthe tu yamunāyāṃ mṛgāvatī //
In the Sahya mountains she is known as Ekavīrā; at Hariścandra she is Candrikā; at Ramaṇā she is worshipped as Ramaṇā; at Rāma-tīrtha she is present as Yamunā; and on the bank of the Yamunā she is revered as Mṛgāvatī.
This verse does not discuss Pralaya; it catalogs sacred places where the Goddess is worshipped under different names, reflecting Puranic sacred geography rather than cosmic dissolution.
Indirectly, it supports the dharma of pilgrimage and honoring local forms of the Divine; for kings and householders, such tirtha-yatra and patronage of shrines is presented in the Puranas as merit-producing conduct.
The verse implies multi-site Devi worship with distinct local names—useful for identifying shrine traditions and planning site-specific rituals (sthala-specific devata-nama), though it gives no explicit Vastu measurements or temple-building rules.
