Skandapurana 1.4.54: adhyāyaḥ 56

Nārada said:

After this I shall describe the supreme liṅga, Brahmeśa,

by merely remembering which the fruit of a Vājapeya sacrifice is attained.

Once in ancient times, O son of Pṛthā, by Brahmā desiring creation,

terrible austerity was well performed for a thousand and a half years.

Pleased by that austerity, Śaṃkara, the lord of Pārvatī,

then granted to him, the creator of the worlds, the boon desired by him.

Then the grandfather of all, delighted, rejoiced, and having fulfilled his purpose,

realizing the māhātmya of the sacred field, himself fashioned a liṅga.

And he dug an auspicious, holy lake named Brahmasaras,

to the east of Mahīnagara, which destroys great sins.

On its bank the all-pervading lord installed the great liṅga;

there the god Śaṃkara himself is visibly present.

The sacred ford named Brahmeśa is greater than Puṣkara, O Phālguna;

having bathed there with devotion, a person should perform the offering of rice-balls (piṇḍadāna),

and make gifts according to his ability, especially on the full moon day of Kārttika,

and should worship the god Brahmeśa with devotion and a glad heart.

His ancestors remain pleased until the dissolution of all beings.

Whatever merit is gained at the Puṣkaras, or in Kurukṣetra during a solar eclipse,

and whatever fruit is obtained by people at the sacred fords such as the Gaṅgā,

that fruit one completely obtains from taking a dip in this sacred ford.

Hear, O son of Pṛthā, the exceedingly wondrous māhātmya of the Mokṣaliṅga.

For the benefit of this place, having propitiated Maheśvara,

the excellent liṅga, Hara named Mokṣeśvara, was installed by me.

Then, O son of Pṛthā, with the tip of a darbha grass blade, I dug a well.

Having propitiated Brahmā, the supreme creator of the worlds,

the Sarasvatī was brought down from the water-pot (kamaṇḍalu) of Brahmā

into this well of the Lord of Liberation, for the deliverance of people from ghosthood (pretatva).

On the fourteenth day of the bright fortnight of the month of Kārttika,

a person who bathes in that well should offer balls of sesame seeds

for the sake of the departed spirits; surely the fruit of the Mokṣatīrtha will be attained.

No departed spirit (preta) is born in his family, O son of Pṛthā; of this there is no doubt.

The departed spirits attain liberation through the power of this sacred ford.

Having bathed with care in the excellent well of Jayāditya, a man...

And bowing to Garbheśvara, he sinks no more into wombs. (17)

This has been set forth by me, O Pārtha, briefly regarding the hidden sacred field.

Whoever hears this entire māhātmya becomes purified; what more should I say? (18)

Thus ends the fifty-sixth chapter, named 'Description of the Māhātmya of Brahmeśvara, Mokṣeśvara, and Garbheśvara', in the Kaumārikākhaṇḍa of the first [section], the Māheśvarakhaṇḍa, in the glorious Skanda Mahāpurāṇa of eighty-one thousand verses. (56)
