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 ||
Vaiśaṃpāyana said: “Because the Grandsire—ancient, all-pervading in spirit—performed sacrifice there in former times, that place came to be renowned as Prayāga, O best of the Bharatas.”
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.
