यत्र साम्बं पुरस्कृत्य भविष्यति कथानकम् । प्रोच्यते तत्पुनर्लोके सांबमेव मुनिव्रताः
yatra sāmbaṃ puraskṛtya bhaviṣyati kathānakam | procyate tatpunarloke sāṃbameva munivratāḥ
O sages of steadfast vows, that narrative to be told with Sāmba placed at the forefront is again known in the world simply as the Sāmba (teaching/Purāṇa).
Sūta (deduced)
Tirtha: Prabhāsa-kṣetra
Type: kshetra
Listener: Muni-vratāḥ / dvija-ṛṣis (assembly of sages)
Scene: A forest-āśrama assembly at Prabhāsa: steady-vowed sages seated in a semicircle as the narrator announces a kathā with Sāmba placed foremost, implying a named scripture-tradition.
Purāṇic teachings are organized around exemplary figures; centering a narrative on a key devotee or hero preserves its intended dharmic message.
The surrounding section is the Prabhāsa-kṣetra Māhātmya; this verse itself focuses on identifying a Sāmba-centered narration rather than a named tīrtha.
None; it identifies a Sāmba-focused narrative tradition.
