Type: sangam
Scene: Two personified rivers—Dharmanadā and Dhūtapāpā—meet in a luminous confluence; pilgrims stand with folded hands as the waters glow with sanctity.

The forming confluence that leads to Pañcanada Tīrtha in Kāśī, beginning with Dharmanadā joining Dhūtapāpā.
Not stated as a command, but the language of ‘sins washed away’ strongly implies snāna (ritual bathing) and tīrtha-sevā at the confluence.
