How does the author of the Shri Sai Satcharitra portray his own role in writing the book within Chapter 45?

In Chapter 45, the author adopts a tone of deep humility, attributing the entire creation of the Satcharitra to the Guru's grace rather than his own skill. He refers to himself as being of "little knowledge" and an "ignorant one" who has been put forward to complete this sacred task. The chapter begins by marveling at Sai Baba's extraordinary skill, who initiated the work while effortlessly grinding grain. The author presents the book as a "speech-sacrifice" that will be completed by the Guru Himself, reinforcing the idea that he is merely an instrument for a divine purpose, a concept central to the message in Chapter 45.
