Why does the author invoke Goddess Saraswati in Chapter 1, and what specific grace is requested from her?

In Chapter 1, the author invokes Goddess Saraswati, the Goddess of Speech and knowledge, recognizing that her grace is absolutely essential for the creation of any literary work. The text poses the rhetorical question, "Without the grace of this Goddess of Speech and Mother of the World, can any literature be achieved?" The author humbly asks her to make his tongue her swan and ride upon it, a poetic request for divine inspiration and eloquence. Ultimately, as detailed in Chapter 1, the specific plea is for Goddess Saraswati to make the author an instrument to effectively share the divine life story, the "nectar of the life," of the capable Sai with all readers.
