Skandapurana 16.51

Īśvara said: / Then, O great goddess, one should go to the Ketu-liṅga of great splendor, / to the north of Rāhvīśāna and to the south of Maṅgalā, 1

situated at a distance of a bow, not very far away; / it is indeed a liṅga of great power, destroying all wicked deeds. 2

The planet named Ketu is extremely fierce, yet suffused with devotion to Śiva; / he is round, extremely vast, and terrifying to behold with one's eyes. 3

Resembling straw smoke, he removes planetary affliction. / There he performed fierce tapas for a hundred divine years, O beloved. 4

Pleased with him, Mahādeva granted him the status of a planet, O beloved, / and the sovereignty over eleven hundred planets. 5

One should worship with devotion the Ketu-liṅga of great splendor situated there; / especially when it is beheld during the terrible rising of Ketu, 6

and during fierce planetary afflictions, one should worship it according to the rule / with flowers, scents, incenses, and various auspicious food offerings. 7

One should duly propitiate the god Ketu, the destroyer of sins. 8

Thus has been briefly described the Ketu-liṅga of great fortune, / which pacifies planetary affliction and destroys all sins. 9

These nine liṅgas of the planets have been told to you; / for the man who sees them daily, whence can there be fear of affliction? 10

In his family no one is born unfortunate, diseased, or sorrowful; / the great planets protect him like a son, O goddess. 11

Thus, O beloved, the fourteen sanctuaries have been described to you properly, / beginning with Vighneśvara and ending with the one established by Ketu. 12

Having heard the māhātmya of the Navagraheśvaras, which destroys sin, / and likewise that of the five liṅgas, one is freed from sins. 13

No unmeritorious man knows the five Mudrā-liṅgas / beginning with Kapardin and ending with Caṇḍanātha. 14

No one else knows the liṅgas of the nine planets / beginning with Sūryeśvara and ending with the Ketu-liṅga. 15

Thus has the group of fourteen sanctuaries been declared; / and whoever knows this with devotion enjoys the fruit of the sacred field. 16

Thus ends the fifty-first chapter, entitled “Description of the Māhātmya of Ketvīśvara,” in the first Prabhāsakṣetramāhātmya of the seventh Prabhāsakhaṇḍa in the glorious Skanda Mahāpurāṇa, a collection of eighty-one thousand [verses]. 51
