Skandapurana 16.80

The Lord said:
To the east of that very [shrine] is a liṅga that destroys sin, / bearing the name Gautameśvara, to the west of Daityasūdana,

situated five bows away, O goddess, granting all desires, / which was worshipped, O spirited lady, by Śalya, the king of Madra.

Then, having worshipped Maheśvara, he performed severe austerity. / Any other person who worships him in like manner

will attain supreme perfection, just like the high-minded Śalya. / He who bathes [the liṅga] with milk on the fourteenth day of the bright half of Caitra,

and then with fragrant water, and worships it with supreme flowers / according to rule with devotion in this way, obtains the fruit of an aśvamedha sacrifice.

Whatever sin has been committed by speech, by mind, or by action, / all of that is destroyed, O goddess, upon seeing that liṅga.

Thus ends the eightieth chapter, named ‘Description of the Māhātmya of Gautameśvara’, in the first Prabhāsa-kṣetra-māhātmya of the seventh Prabhāsa section, in the Skanda-Mahāpurāṇa consisting of eighty-one thousand verses.
