Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
अश्वतीर्थं च विख्यातम् अनन्तं श्राद्धदानयोः तीर्थं वेदशिरो नाम तथैवौघवती नदी //
aśvatīrthaṃ ca vikhyātam anantaṃ śrāddhadānayoḥ tīrthaṃ vedaśiro nāma tathaivaughavatī nadī //
And the well-known Aśva-tīrtha is declared inexhaustible in its reward for rites of śrāddha and charitable giving. Likewise, (there is) the sacred ford named Vedaśiras, and also the river called Oghavatī.
This verse does not address pralaya; it focuses on sacred geography (tīrthas) and declares the merit from performing śrāddha and dāna at Aśva-tīrtha to be “ananta” (inexhaustible).
It supports the householder and royal duty of sustaining dharma through ancestor-rites (śrāddha) and charitable giving (dāna), recommending specific tīrthas where these acts are considered especially fruitful.
The ritual significance is primary: the verse highlights tīrtha-based efficacy—Aśva-tīrtha is said to yield inexhaustible results for śrāddha and dāna—while also identifying Vedaśiras (a sacred ford) and the Oghavatī river as notable pilgrimage loci.
