ब्रह्मांडोदरवर्तीनि यानि तीर्थानि सर्वतः । ऊर्जे यत्र समायांति स्वाघौघ परिनुत्तये
brahmāṃḍodaravartīni yāni tīrthāni sarvataḥ | ūrje yatra samāyāṃti svāghaugha parinuttaye
Whatever sacred fords exist throughout the whole expanse of the cosmos, they all gather there in the month of Ūrja, to drive away their own accumulated sin.
Skanda (deduced: Kāśīkhaṇḍa commonly Skanda → Agastya)
Tirtha: Pañcanada (as tīrtha-sammelana-sthāna)
Type: sangam
Scene: A visionary tableau: tīrthas from across the cosmos appear as radiant sages and river-deities traveling through the sky to Kāśī, descending upon Pañcanada in the Ūrja month, washing away dark ‘sin-clouds’.
Kārtika (Ūrja) magnifies tīrtha-power: it is portrayed as a time when sacred forces converge for purification.
The site ‘where all tīrthas assemble’—understood from context as Pañcanada and its Kāśī tīrtha-zone.
Observance in Ūrja (Kārtika) is implied, especially tīrtha-sevā centered on bathing/purification.
