Avanti–Narmadā–Puṣkara Tīrtha-Kathana (धौम्यकथितं तीर्थवर्णनम्)
यत्रायजत भूतात्मा पूर्वमेव पितामह: । प्रयागमिति विख्यातं तस्माद् भरतसत्तम
yatrāyajata bhūtātmā pūrvam eva pitāmahaḥ | prayāgam iti vikhyātaṃ tasmād bharatasattama ||
பரதர்களில் சிறந்தவனே! முன்னொரு காலத்தில் அனைத்திலும் நிறைந்த ஆத்மாவுடைய பிதாமகன் அங்கே யாகம் செய்ததால், அந்த இடம் ‘பிரயாகம்’ என்று புகழ்பெற்றது।
वैशम्पायन उवाच
The verse grounds a sacred place’s authority in exemplary ancient ritual: a tīrtha becomes revered because foundational figures performed yajña there, linking geography with ethical memory, tradition, and the pursuit of merit.
Vaiśaṃpāyana explains the etymic and reputational basis of the place-name “Prayāga,” stating that it is famous because the Grandsire (Pitāmaha, i.e., Brahmā) once performed sacrifice there.
