What assistance does the author seek from Goddess Saraswati in Chapter 1, and why is her grace considered essential?

In Chapter 1, the author pleads for assistance from Goddess Saraswati, the daughter of Brahma and the goddess of speech. He asks her to 'make my tongue your swan and ride upon it,' essentially requesting her to inspire his words. Her grace is considered absolutely essential, as the author questions, '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 sees her as the Mother of the Universe and the Vedas and hopes she will make him the instrument to narrate the nectar-like life story of Sai for the benefit of everyone.
