According to Chapter 1, what is the role of Goddess Saraswati and how is her grace sought for writing the book?

In Chapter 1, Goddess Saraswati is revered as the Goddess of Speech and the Mother of the World, whose grace is considered absolutely essential for any literary creation. The author describes her as the daughter of Brahma, who holds the Brahma-veena and rides a swan. He 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?' The author then implores her to make him the instrument to narrate the life of Sai. Interestingly, this chapter also presents a powerful non-dual concept by stating, 'Sai himself is Goddess Saraswati,' suggesting that Sai is the ultimate source of the inspiration and ability to write about his own life.
