The Goddess creates the three gods to do the work of creation, preservation and destruction, carries them to her island Manidvipa, turns them into women for a hundred years, and returns them with their consorts to their tasks.
The Devi Bhagavata makes the Goddess the maker of the triad. Having created Brahma, Vishnu and Shiva for the three cosmic tasks, she has them carried in a flying car to Manidvipa, her island of gems in the ocean of nectar, a realm higher than Goloka, Vaikuntha, Kailasa or Brahmaloka. There, in a land of women ruled by the Goddess, the three become women themselves and for a hundred years do not know who they are. When she restores them she tells them there is no difference between herself and the Purusha, gives them Saraswati, Lakshmi and Parvati as consorts, and sends them back to their work. The same book describes the birth of the Tridevi — Mahasaraswati, Mahalakshmi and Mahakali — as the three qualities of nature.
What is different here:
Base telling of this frame; the three gods are creatures of the Goddess and their consorts are her portions.
