How does the author of the Satcharitra express his own role and humility in the composition of Chapter 45?

In Chapter 45, the author expresses profound humility regarding his role in writing the Satcharitra. He begins by noting the extraordinary skill of Sai Baba, who initiated the writing of the book. The author positions himself as a person of "little knowledge" when compared to the "all-knowing listeners" or readers. He refers to his work as a "speech-sacrifice (Vag-yagna)" and humbly asks that it be accepted with a grateful heart. As conveyed in Chapter 45, the author sees himself merely as an instrument, stating that this auspicious work is being completed by the Guru, who has simply put an "ignorant one like me forward."
