Skandapurana 5.137

The seers said: / What austerity, meditation, and the like was performed by Dharmarāja / for the destruction of Māṇḍavya's curse? Proclaim that to us!

Sūta said: / Having incurred the curse of Māṇḍavya, Dharmarāja was deeply afflicted with sorrow; / residing in that sacred field, O best of the twice-born, he performed austerity.

Having constructed a temple for the God of gods, the matted-haired Śiva, / he worshipped him without distraction with flowers, incenses, and ointments.

Then, after a long time, Maheśvara was pleased with him / and said: “I am the giver of boons; ask for whatever is desired.”

Dharmarāja said: / O God, previously I was cursed by the high-souled Māṇḍavya, / even while abiding by my own duty and being completely free of fault.

And by him, being enraged, it was said: “You will be born in the womb of a Śūdra!”

“And even there, born of my curse, you will directly obtain great suffering / arising from the destruction of your kin, suffering caused by that birth.”

Therefore, save me, O best of gods, from that womb! / And being such as I am, how can I take birth in it?

And even there, great suffering arises from the destruction of kin. / For this sake, O best of gods, you have been worshipped by me.

The Holy One said: / The word of that true sage cannot be made otherwise; / therefore, though having become a Śūdra, you shall not incur suffering.

Even upon witnessing the destruction of your kin, you will not experience grief at all, / because even when restrained, they will not heed your word.

For this reason, there will be no grief in your mind / arising from kin, O Dharmarāja; this is the absolute truth spoken by me.

Having lived for a hundred years, O wise one, as a Śūdra devoted to righteousness, / having given many teachings to your kin out of a desire for their welfare, / even though they are ever devoid of faith and sinful in nature,

then, when the hundred years are complete, solely through the gateway of Brahman, / thoroughly releasing yourself, you will attain liberation alone.

Having spoken thus, the Lord then vanished from sight; / and Dharmarāja accepted that curse born of Māṇḍavya.

Then, having descended to the surface of the earth in the form of Vidura, / that highly intelligent one made the word of Māṇḍavya come true.

Born directly from the Lord Vyāsa of immeasurable splendour, / the son of Parāśara, a brahmin, he was born from the womb of a maidservant.

This entire narrative concerning Dharmarāja, which destroys all sins, / about which I was asked, has been related to you.

Thus ends the one hundred thirty-eighth chapter, entitled “Description of the Origin of Dharmarājeśvara,” in the Nāgarakhaṇḍa, the sixth [part] of the Māhātmya of the Hāṭakeśvara Sacred Field, in the eighty-one-thousand-verse collection of the glorious Skanda Purāṇa.
