Why does the author invoke Goddess Saraswati in Chapter 1, and what is her connection to Sai Baba?

The author invokes Goddess Saraswati, the daughter of Brahma, as she is the Goddess of Speech and the Mother of the World, without whose grace no literature can be achieved. Chapter 1 details a prayer to her, asking her to make the author's tongue her swan and to make him an instrument to share the nectar of Sai's life with everyone. The text then beautifully equates Sai with the goddess, proclaiming, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story for the salvation of his devotees,' highlighting the divine inspiration behind the Satcharitra.
