According to Chapter 1, why does the author invoke Goddess Saraswati, and how is she connected to Sai Baba?

The author invokes Goddess Saraswati in Chapter 1 because she is the goddess of speech and knowledge, and her grace is considered essential for writing any literature. The author bows to her, asking her to 'make my tongue your swan and ride upon it,' effectively requesting her to guide his words. As explained in this chapter, a profound connection is also made to Sai Baba, with the author stating, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story for the salvation of his devotees.' This shows that the author sees Sai as the embodiment of the divine principle of knowledge.
