Can you explain the role and description of Goddess Saraswati as presented in the initial chapter of Sai Satcharitra?

In the first chapter of the Sai Satcharitra, the author offers salutations to Goddess Saraswati, the daughter of Brahma, recognizing her as essential for the creation of any literary work. She is described as a 'wave of cleverness' who holds the Brahma-veena, wears red vermillion on her forehead, rides a swan, and is dressed in white clothes. The author acknowledges that without the grace of this 'Goddess of Speech and Mother of the World,' writing the book would be impossible. As Chapter 1 highlights, the author prays for her to make him an instrument to share the nectar of Sai's life. Furthermore, the text equates Sai Baba with the goddess, stating, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story for the salvation of his devotees.'
