Skandapurana 16.108

Īśvara said:
Then, O great goddess, one should go to the excellent liṅga of the Vasus, / located in the north-east direction from Someśa at a distance of fifty bows. 1

Situated [there], O great goddess, is the four-faced liṅga dear to the gods, / named Pratyūṣeśvara, which destroys great sins. 2

From the darśana of that god, the sin arising from seven births / comes to destruction; truly, truly, O fair-faced one! 3

The goddess said:
Who is this one named Pratyūṣa, and how was the liṅga consecrated? / Whose son is he known to be? Tell me this, O Śaṃkara! 4

Īśvara said:
Dakṣa, the son of Brahmā, O goddess, is remembered as a Prajāpati. / Formerly he gave ten of his sixty daughters to Dharma. 5

Among them, O great goddess, one is renowned as Viśvā. / And she, O great goddess, bore eight sons to Dharma: 6

Āpa, Dhruva, Soma, Dhara, Anala, Anila, / Pratyūṣa, and Prabhāsa—these are celebrated as the eight Vasus. 7

Among them, that seventh one is renowned as Pratyūṣa. / Desiring a son, O queen of gods, he came to the sacred field of Prabhāsa. 8

Knowing it to be a sacred field that fulfills desires, he consecrated Maheśvara / and performed vast austerity for a hundred divine years, O beloved, / meditating on the god, Mahādeva, tranquil, with his mind fixed upon him. 9

Then Mahādeva, the taintless one, pleased by his devotion, / gave him a son, O goddess: Devala, the best of yogins. 10

From that time forward, O queen of gods, through the power of that liṅga, / the venerable yogin Devala became the son of Pratyūṣa. 11

For this reason it is designated as Pratyūṣeśvara. 12

And whatever childless man worships it— / in his lineage, O queen of gods, offspring will never fail. 13

Whoever, at dawn, O great goddess, worships the supreme Pratyūṣeśvara / constantly with true devotion and a restrained mind, / his sin, even that arising from the slaughter of a brahmin, will come to an end. 14

A bull should be given right there by those who desire the full fruit of the pilgrimage. 15

One should keep vigil there at night on the fourteenth day of the dark fortnight of Māgha; / through keeping vigil, one obtains the fruit of all charitable gifts and sacrifices. 16

Thus ends the one hundred and eighth chapter, entitled “Description of the Māhātmya of Pratyūṣeśvara,” in the first part, the Prabhāsakṣetramāhātmya, of the seventh section, the Prabhāsakhaṇḍa, in the glorious Skandapurāṇa, a compendium of eighty-one thousand verses. 108
