Skandapurana 16.224

Īśvara said: / Then, O great goddess, one should go to the liṅga installed by Indra, / richly endowed with the name Pāpamocana, south of Puruṣottama.

Long ago, having slain Vṛtra, Śakra, joined with [the sin of] brahmin-slaughter, / said to the divine seers: 'How will this go away?

Indeed, brahmin-slaughter is dreadful to behold, causing discoloration in me, / moving with a foul smell, and destroying all brilliance.'

Then the hosts of gods and the great seers headed by Nārada said to him: / 'Go to Prabhāsa, O lord of gods, for that is a sacred field that takes away sins.

Having worshipped Mahādeva there, you will be freed from brahmin-slaughter.' / Promising, 'So be it,' he went there, O lovely-faced one.

He established a liṅga of the god of gods, the wielder of the trident; / he was constantly devoted to its worship with incenses, scents, and ointments.

Then the foul smell of his body quickly went to destruction; / all his discoloration vanished, and his body became supreme.

Then, becoming joyful in mind, he spoke these words: / 'Whichever person, having come here, worships this [liṅga] with devotion,

his sin consisting of brahmin-slaughter and the like will go to destruction.' / Having spoken thus, the thousand-eyed [Indra], exceedingly glad, went to heaven,

freed from brahmin-slaughter and worshipped by the denizens of heaven. / The gift of a cow is to be given there to a brahmin who has mastered the Vedas; / to remove brahmin-slaughter, one should perform a śrāddha there.

Thus ends the two hundred and twenty-fourth chapter, named 'Description of the Glory of Indreśvara', in the first [part], 'Glory of Prabhāsakṣetra', in the seventh [book], Prabhāsakhaṇḍa, of the venerable Skandapurāṇa, a collection of eighty-one thousand [verses]. // 224
