Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
शतरुद्रा शताह्वा च तथा विश्वपदं परम् अङ्गारवाहिका तद्वन् नदौ तौ शोणघर्घरौ //
śatarudrā śatāhvā ca tathā viśvapadaṃ param aṅgāravāhikā tadvan nadau tau śoṇaghargharau //
There are rivers named Śatarudrā and Śatāhvā; likewise (the river called) Viśvapada, the supreme holy station; and Aṅgāravāhikā. In the same way, the two rivers are known as Śoṇa and Gharghara.
This verse is not about Pralaya; it catalogs sacred river-names, indicating the Purana’s tirtha-focused mapping of holy landscapes rather than cosmological dissolution.
By preserving and publicizing sacred geography, the text supports dharmic life: householders gain guidance for pilgrimage and ritual bathing, while kings are implicitly encouraged to protect tirthas and riverine routes that sustain religious practice.
The ritual takeaway is tirtha-orientation: these named rivers function as sanctioned sites for snāna (ritual bathing), dāna (charity), and pilgrimage observances, which often anchor temple and ghat traditions along their banks.
