Skandapurana 16.74

Īśvara said: / Then, O great goddess, one should go to the excellent Śākalyeśvara, / situated thirty bow-lengths to the northwest of Daityasūdana.

It was worshipped by Śākalya, O great goddess, granting all desires; / where the royal sage named Śākalya, having performed great austerity,

and having propitiated Mahādeva, brought Bhava before his eyes; / he caused that pleased Maheśvara to descend into the liṅga.

When it is seen, O fair-hipped one, the sin committed by men during seven births / quickly perishes, like darkness at the rising of the sun.

There, on the eighth and fourteenth lunar days, one should bathe Śiva with milk, / and worship him according to rule with perfumes, flowers, and other offerings in due order.

Gold should be given there by those desiring the full fruit of the pilgrimage. / Hear from me its four names as they are being told:

First, in the Kṛta age, O goddess, it was celebrated as Bhairaveśvara. / Then it was properly worshipped by the Manu Sāvarṇi, O dear one;

in the Tretā age, it was designated by the name Sāvarṇikeśvara. / Then, in the Dvāpara age, O goddess, by the noble Gālava / the Bull-bannered One was worshipped properly there in the form of a liṅga.

The third [name] of that god was designated as Gālaveśvara. / But when the Kali age arrived, indeed a sage named Śākalya [came],

wherein he attained perfection and sovereignty, such as the power of atomicity; / hence its fourth [name] became known by the name Śākalyeśvara.

Thus the name in the four ages of that liṅga has been proclaimed; / it destroys sin, grants religious merit to men, and is proclaimed to bestow all desires.

Hear, O beloved, the origin of the field of that very god of gods.

Its circumference is eighteen bow-lengths all around, O goddess; / it removes great sins, O goddess, for those who dwell in that field.

It grants liberation even to worms, insects, winged creatures, and animals. / The water in the wells and other [reservoirs] there is considered sārasvata.

Bathing wherever he may there, a man is glorified in the heavenly world. / The fruit of a thousand horse-sacrifices and a hundred Vājapeya sacrifices—

that fruit he fully obtains from the darśana of that liṅga. / When the lunar festival arrives, he who is pure and self-controlled there,

and properly recites the Aghora [mantra] accompanied by burnt offerings of clarified butter, / remaining near that liṅga until the period of a month is fulfilled, O dear one,

even though possessed of great sins or tainted with secondary sins, / he attains all supreme perfection, O woman of excellent complexion.

That liṅga is remembered as fulfilling desires, granting the fruit of all wishes; / the face of the god situated there is the great Aghora, the terrifying one.

Formerly on earth it was known by the name Bhairaveśvara; / but when this age arrived, it became named Śākalyeśvara. / Thus ends the seventy-fourth chapter, named 'The Description of the Māhātmya of Śākalyeśvara,' in the first [part], the Prabhāsakṣetramāhātmya, in the seventh [section], the Prabhāsakhaṇḍa, in the glorious Skanda Mahāpurāṇa containing eighty-one thousand verses.
