Based on Chapter 1, why does the author invoke Goddess Saraswati, and what specific grace does he seek from her?

The author invokes Goddess Saraswati in Chapter 1 out of a sense of humility and recognition of the immense challenge of writing the Sai Satcharitra. He questions how any literature could be achieved without the grace of the Goddess of Speech, asking, "How could I write this book?" He seeks her direct intervention, praying that she, as a "wave of cleverness," will make his tongue her swan and ride upon it. As Chapter 1 elaborates, the specific grace he seeks is for her to make him the instrument to "feed the nectar of the life of the capable Sai to everyone," acknowledging her as the mother of knowledge and virtues.
