Skandapurana 16.185

Īśvara said: / Then one should go, O great goddess, to Devamātā, the imperishable, / in the south-western direction from Maṅkīśa, having assumed the form of Gaurī. / She is sung among the worlds as the Devamātā of Sarasvatī.

There the goddess Sarasvatī is seated upon sandals, / having assumed her form resorting to the submarine mare in the form of Gaurī.

Like a mother, the gods were protected [by her] from fear of the submarine fire. / Therefore she was made [famed as] Devamātā by the gods in this world.

Whatever man worships her on the third day in the month of Māgha, / or a chaste woman who is self-controlled, will attain all desires.

And whoever feeds a married couple with rice-pudding, sugar, and other sweets / attains the fruit of giving food to a thousand forms of Gaurī.

A pair of gold sandals should be given there to a virtuous brahmin.

Thus ends the one hundred and eighty-fifth chapter, entitled "Description of the Māhātmya of Devamātṛgaurī," in the first [section, named] Prabhāsakṣetramāhātmya, of the seventh [section, named] Prabhāsakhaṇḍa, in the Skandapurāṇa Mahāpurāṇa of eighty-one thousand verses.
