Saraswati

Sarasvati, Saraswati (Sanskrit) The ethereal, the elegant one; the divine consort or wife of Brahma, his feminine alter ego, a later form or aspect of Vach (voice or the Word), a title of the Third Logos in Greece as well as in India. This parallels the Bath Qol (daughter of the voice, daughter of the Word) of mystical Hebrew thought, which can be taken either as the feminine aspect of the Logos itself, or as its daughter -- the inspiration flowing forth from, or the feminine or vehicular side of, the Logos. The goddess of hidden learning and esoteric wisdom, Sarasvati is usually shown riding on a peacock with its tail spread. She is similar to the Gnostic Sophia, to the Sephirah of the Hebrew Qabbalah, and to the Holy Ghost of the Christians. 
Sarasvati is also a sacred river spoken of in the Vedas, and as a river goddess she was often invoked to bestow vitality, renown, and riches; elsewhere she is described as moving along a golden path and as destroying the monster-demon Vritra. 

Sarasvati's esoteric meaning is know through Atma yoga
