Skandapurana 16.306

Īśvara said: / Next, O great goddess, one should go to the unsurpassed Sāmbāditya, / situated north of that, which destroys all sins;

Where Sāmba, having performed austerity and worshipped the Maker of Day, / attained a beautiful body through the grace of the thousand-rayed sun.

When cursed in anger by his father, Sāmba, the son of Jāmbavatī, / then worshipped Viṣṇu, whose eyes are like lotus petals.

To show favor regarding the curse upon Sāmba, the son of Jāmbavatī, / Viṣṇu, with a benevolent countenance, spoke to him:

“Go to the Prabhāsa kṣetra, to the unsurpassed share of Brahmā / on the delightful bank of the Ṛṣitoyā, adorned by brahmins;

There, in the form of Sūrya, I will bestow a boon, my son.” / Addressed thus at that time by the mighty Viṣṇu,

he went to the Prabhāsa kṣetra, to the delightful, auspicious Śivapura. / There, having worshipped the supreme deity, the sun, the stealer of waters,

he propitiated him then, praising him with various hymns.

Ravi replied to Sāmba: “I am pleased with your hymn indeed; / go quickly, O best of men, to the auspicious bank of the Ṛṣitoyā.”

Addressed thus, he then went to the auspicious bank of the Ṛṣitoyā, / where the brahmin seer Nārada was performing austerity.

Having gone there, the son of Hari said these words / to those brahmins who were residents of the elevated place:

Sāmba said: / “This indeed is the share of Brahmā in the excellent kṣetra of Prabhāsa; / those who are brahmins here are considered the foremost on earth.

At your word, O brahmins, I will worship the sun; / this place was previously indicated to me indeed by Viṣṇu.”

The brahmins said: / “You will attain success, O Sāmba! Worship the Maker of Day.” / Thus spoken to by the brahmins, he then approached the Maker of Light;

Sāmba, the son of Jāmbavatī, worshipped him daily. / And seeing him devoted to austerity, the great and compassionate Viṣṇu,

filled with parental affection, reflected upon this: / “Just as Rudra grants sovereignty and Viṣṇu grants liberation;

Just as the king of gods, worshipped with sacrifices, is remembered as the bestower of heaven; / just as water combined with clay and ash is a purifier; / just as fire has burning for its nature, and Gaṇeśvara removes obstacles;

Just as the daughter of Brahmā grants spontaneous eloquence to mortals; / even so, there is no deity other than the Maker of Day who bestows health.

Although worshipped in various ways, that deity, the pure Maker of Light, / does not grant the boon only because of my curse.”

Having reflected thus, the blessed, lotus-eyed Viṣṇu, Janārdana, / pleased with him, took the form of the sun;

He who is known as another Nārāyaṇa, abiding right beside him, / then became visible—Viṣṇu, possessing the form of Sūrya, the Maker of Day; / the granter of boons to doers of meritorious deeds spoke, exceedingly pleased:

“Enough of your hardship, O Sāmba! For what purpose do you perform austerity? / I am pleased, O son of Hari! Choose a boon, O you of noble vows!”

Sāmba said: / “O God, Lord of Gods, visible ornament of the sky, / by your grace may I become pure, my body freed from leprosy! / Abiding in this delightful place, be ever present here!”

Sūrya said: / “Now your body will become pure, O Sāmba! / Whatever man comes here on a Sunday that is a seventh lunar day, / dedicated to fasting and staying awake during the night,

the eighteen forms of leprosy as well as diseases born of sin / will never occur in the family of that noble soul.

Whatever man, having performed his ritual ablution, full of devotion and with subdued senses, / worships Sāmbāditya of great radiance on a Sunday, / that man becomes free of disease, wealthy, and possessed of sons.

Directly to the east of it, tending slightly toward the northeast, / is an auspicious pool that removes sins, filled with pure water.

The wise man, having bathed there according to rule, should perform the ancestral rite; / and whoever feeds brahmins and worships Sāmbāditya,

having all desires fulfilled within himself, is glorified in the world of the sun.”

Thus ends the three hundred and sixth chapter, entitled "The Description of the Māhātmya of Sāmbāditya," in the first [part], the Prabhāsakṣetramāhātmya, of the seventh section, the Prabhāsakhaṇḍa, in the glorious Skanda Mahāpurāṇa, a collection of eighty-one thousand [verses].
