Goddess Gayatri is also worshipped as the Hindu Trimurti. Some also consider her to be the mother of all Gods and the culmination of Lakshmi, Parvati and Sarasvati.
Gayatri Devi is an incarnation of Saraswati Devi, consort of Lord Brahma, symbolising the “shakti” (strength) and “dev” (quality) of Knowledge, Purity and Virtue. Saraswati Devi is held to be the patronness of the Arts, being a poet and musician, as well as skillful composer. In the form of Gayatri Devi, with the blessings of Lord Brahma, she is believed to have given the four Vedas to mankind.
Gayatri, Savitri and Saraswati are three goddesses representing the presiding deities of the famous Gayatri mantra chanted thrice a day. Gayatri is the presiding deity of the morning prayer and rules over the Rigveda and the garhapatya fire. Every grihasta (householder) was expected to keep 5 or 3 sacred fires ( Five fires: ahavaneeya, dakshagni, garhapatya, sawta, aavasadha.) in his house to perform Vedic rituals.
