अर्बुदस्य च यत्षड्भिस्तत्फलं च भविष्यति । वस्त्रापथस्य तिसृभिर्गंगायाः पंचभिश्च यत्

And that very merit will arise as though one had performed six pilgrimages to Arbuda, three to Vastrāpatha, and had gained fivefold the merit of the sacred Gaṅgā—
Dharma (personified), extending the tīrtha-merit equivalences
Scene: A mountain shrine on Arbuda rises above forests; a pilgrim-path (vastrāpatha) winds like a ribbon; in the sky a personified Gaṅgā pours a stream of light, signifying ‘five Gaṅgās’ worth of merit converging into the focal site’s blessing.
The Purāṇa magnifies a local tīrtha’s sanctity by equating it with multiple celebrated tīrthas, including the Gaṅgā.
Stambhatīrtha, by comparison with Arbuda, Vastrāpatha, and the Gaṅgā.
Not explicit here; the context remains the fruits of tīrtha-acts (snāna/dāna/yātrā) at Stambhatīrtha.
