Based on the first chapter, what is the role of Goddess Saraswati in the creation of the Sai Satcharitra?

As detailed in Chapter 1, Goddess Saraswati, the daughter of Brahma, plays a crucial role as the Goddess of Speech and knowledge. The author invokes her, asking her to make his tongue her swan and ride upon it, acknowledging that without her grace, no literature can be achieved. Her role is to be the divine inspiration and facilitator for writing the book. The text further elevates this connection by stating that "Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story for the salvation of his devotees," implying that Sai is the ultimate source of the knowledge being transcribed.
