Skandapurana 5.172

The seers said: / "Ah, indeed, great was the marvel of Viśvāmitra, the true muni, / by whom that water was turned into blood through the power of mantras!

Relate how water was restored from that time on / to Sarasvatī, O fortunate one; tell everything in detail."

Sūta said: / "For a long time, O best of brahmins, that current of Sarasvatī / remained a great [stream] of blood, frequented by ghosts and rākṣasas.

Then after some time, Vasiṣṭha, the best of munis, / who was dwelling on Arbuda, was addressed by her, wretched and filled with grief:

'For your sake, O muni, I was cursed in anger by Viśvāmitra; / I have become a bearer of a torrent of blood, abandoned by ascetics.

Therefore, grant me your grace, O chief of brahmins, so that water may again / flow in my current, and the blood come to an end.

In the creation, destruction, or maintenance of the three worlds, O brahmin, / there is indeed no inability in you, O lord of all munis!'"

Vasiṣṭha said: / "I shall act in such a way, O auspicious one, that water will again appear / in your current, and all the blood will perish."

Having spoken thus, that brahmin seer descended to the surface of the earth / and went to the plakṣa tree from which Sarasvatī had descended.

Entering into deep meditation there, he sat on the surface of the earth, / having felt great perplexity on account of Viśvāmitra.

Looking at the surface of the earth with a mantra dedicated to Varuṇa, / abundant water broke through the earth and burst forth,

through two openings, O chiefs of brahmins, because of the gaze of his two eyes. / The water of one [opening] swiftly went to where Sarasvatī was born,

and then at the root of the plakṣa tree, it carried off by force / that blood with its momentum; then the great river was filled with that [water].

And the second current, which issued forth from his agitation, / became the river named Sābhramatī on the surface of the earth.

Thus Sarasvatī returned to her natural state once again, / concerning which I was questioned by you, O fortunate brahmins, for the sake of Sarasvatī.

Whoever reads or hears this narrative named after Sarasvatī, / which grants great intellect, their mind increases / by the grace of Sarasvatī; this truth has been spoken by me.

Thus ends the one hundred and seventy-third chapter, entitled 'Description of the Deliverance of Sarasvatī from the Curse and the Origin of Sābhramatī,' in the narrative of Sarasvatī in the māhātmya of the sacred field of Hāṭakeśvara in the Nāgarakhaṇḍa, the sixth [part] of the auspicious Skanda Mahāpurāṇa, in the collection of eighty-one thousand verses.
