tato māṃ devatāḥ svarge martyaloke ca mānavāḥ /
stuvanto vyāhariṣyanti satataṃ raktadantikām //

The goddess spoke:
When the twenty-eighth age has arrived, in the Vaivasvata Manvantara, two other great Asuras shall be born, Śumbha and Niśumbha. Then born as the offspring of Yaśodā’s womb in the cowherd Nanda’s house, and dwelling on the Vindhya mountains, I will destroy them both. And again becoming incarnate in a very terrible form on the face of the earth, I will slay the Vaipracitta[22] Dānavas; and when I devour those fierce and great Vaipracitta Asuras, my teeth shall become red like the flowers of the pomegranate. Hence the gods in Svarga and men in the world of mortals praising me shall always talk of me as “Red-toothed.”[23]
