उपरिष्टाद्बकैर्हंसैर्भ्रममाणैः समंततः । आटिभिर्मद्गुभिश्चैव समन्ताज्जलपक्षिभिः
upariṣṭādbakairhaṃsairbhramamāṇaiḥ samaṃtataḥ | āṭibhirmadgubhiścaiva samantājjalapakṣibhiḥ
All around—above and on every side—the sky and waters teemed with water-birds: cranes and swans circling, and other aquatic fowl such as the āṭi-birds and madgu, moving everywhere in that sacred region.
Narrator (contextual Purāṇic narration; likely Sūta/Lomaharṣaṇa in a māhātmya frame)
A tīrtha is recognized not only by doctrine but by auspicious atmosphere—nature itself appears harmonious and sanctified.
The verse sets the scene for a riverine tīrtha/āśrama landscape in the Nāgarakhaṇḍa’s Tīrthamāhātmya, without naming the site in this line alone.
None explicitly; it is a descriptive marker of a sacred place.
