Skandapurana 16.159

Īśvara said: / Then, O great goddess, one should go to the unsurpassed Ratnakuṇḍa, / situated on the southern side of Ratneśa at a distance of seven bows, / which alleviates great sins and was fashioned by Viṣṇu himself.

Eighty million sacred fords moving on earth, in heaven, and in the atmosphere / were brought together by Kṛṣṇa and cast there in abundance.

A crore of Gaṇas protects that kuṇḍa, O beloved; / when the Kali age has arrived, it is hard to attain for those whose minds are undisciplined.

Having bathed there, O great goddess, by an act observed according to rule, / one attains a hundredfold the fruit of a horse sacrifice.

Especially on the eleventh lunar day, one should offer the piṇḍa there; / his ancestors attain imperishable satisfaction, O passionate woman.

One should keep a night-vigil there on the eleventh lunar day according to rule; / one obtains what is desired, O goddess, if one's faith is firm.

Yellow clothes should be given, as well as a milch cow, / there in honour of Viṣṇu, for attaining the full fruit of the pilgrimage.

In the Kṛta age it is called Hemakuṇḍa, in the Tretā age named Raupya; / in the Dvāpara age it is Cakrakuṇḍa, and in the Kali age it is remembered as Ratnakuṇḍa.

Numerous streams of the Gaṅgā flowing in Pātāla / were brought there by Hari and remain there, O passionate woman.

By bathing there, O ruler of the gods, there is ablution in all sacred fords.

Thus ends the one hundred and fifty-ninth chapter, named "Description of the Greatness of Ratneśvara", in the first [part], the "Prabhāsakṣetramāhātmya", in the seventh section, the "Prabhāsakhaṇḍa", of the glorious Skandamahāpurāṇa, a compendium of eighty-one thousand [verses].
