Based on Chapter 1, what is the significance of Goddess Saraswati, and why does the author invoke her?

Chapter 1 highlights Goddess Saraswati as the daughter of Brahma and the goddess of speech, knowledge, and virtues. She is described as holding the Brahma-veena, riding a swan, and being the mother of the Vedas. The author invokes her because, as the text asks, "Without the grace of this Goddess of Speech and Mother of the World, can any literature be achieved?" The author prays for her to be the instrument to share the nectar of Sai's life. The chapter further deepens this connection by stating that Sai himself is also Goddess Saraswati, singing his own life story for the salvation of devotees.
