Based on Chapter 1, what role does Goddess Saraswati play in the creation of the Satcharitra, and how is she identified with Sai?

In Chapter 1, the author invokes Goddess Saraswati, the daughter of Brahma, as essential for the creation of literature. Acknowledging her power, the author asks, 'Without the grace of this Goddess of Speech and Mother of the World, can any literature be achieved? How could I write this book?' He prays for her to make him an instrument to share the nectar of Sai's life. The text beautifully merges her identity with Sai Baba by declaring, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story for the salvation of his devotees.' This passage from Chapter 1 shows that Sai is not only the subject of the book but also the divine inspiration and power of speech enabling its creation.
