Skandapurana 16.249

Īśvara said: / Then, O great goddess, one should go to the god Saṃgameśvara, / renowned as Golakṣa, the destroyer of all sins,

in its western part, bestowing the fruit of all desires. / In ancient times there was a seer named Uddālaka of great austerity.

Formerly, having reached the confluence of Sarasvatī and Piṅgā / that destroys all sins, he performed austerity, O queen of gods.

Then, as that great-souled one endowed with devotion was performing severe austerity, / a liṅga indeed rose up before him, O beautiful one.

At that very moment, a bodiless voice spoke: / 'O mighty-armed Uddālaka, listen to this word of mine!

From this day forth my dwelling here will be perpetual. / Since this supreme liṅga arose here at the confluence, / its name shall indeed be Saṃgameśvara.

Those men who, having bathed here at the world-renowned confluence, / behold Saṃgameśvara, go to the supreme state.'

Īśvara said: / Then he worshipped it day and night without wearying; / then, at the end of his body, he went to where Maheśvara is.

Thus ends the two hundred and forty-ninth chapter, named 'Description of the Glory of Saṃgameśvara,' in the first [part], 'Glory of the Prabhāsa Field,' of the seventh [book], Prabhāsakhaṇḍa, in the glorious Skanda Mahāpurāṇa consisting of eighty-one thousand verses.
