What role does Goddess Saraswati play in the writing of the Sai Satcharitra, according to Chapter 1?

According to the invocations in Chapter 1, Goddess Saraswati, the Goddess of Speech, is crucial for the creation of the Sai Satcharitra. The author bows to her, asking her to 'make my tongue your swan and ride upon it.' The text poses a rhetorical question: 'Without the grace of this Goddess of Speech and Mother of the World, can any literature be achieved? How could I write this book?' She is seen as the Mother of the Universe and the Vedas, and the author prays for her to make him an instrument to share the nectar of Sai's life. The chapter also identifies Sai himself with Goddess Saraswati, suggesting he is the ultimate source of his own life story.
