Skanda (deduced: Kāśīkhaṇḍa typically Skanda → Agastya)
Tīrtha-māhātmya is linked with the lives of great ṛṣis: purity of place is intertwined with purity of tapas and Vedic character.
Indirectly Pañcanada, through the opening of its origin narrative involving the sage Vedaśiras.
None explicitly; the verse establishes the authority of the narrative by introducing a Veda-like sage.
