Why does the author of the Sai Satcharitra offer salutations to Goddess Saraswati in the first chapter?

The author offers salutations to Goddess Saraswati in Chapter 1 because she is the Goddess of Speech and knowledge, and her grace is considered indispensable for any literary endeavor. The author expresses deep humility, questioning, "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 prays for her to make his tongue her swan and to make him an instrument to narrate the life of Sai Baba. As Chapter 1 reveals, this invocation is crucial for the author to feel empowered to write the sacred text for the salvation of devotees.
