How does the author of the Sai Satcharitra describe his own role in composing the text in Chapter 30?

In Chapter 30, the author expresses profound humility, viewing himself as merely an instrument for a divine task. He questions his own qualifications by asking, "what qualification do I have?" The author firmly believes that Sai Baba is the true originator and that "He whose work it is, He Himself gets it accomplished." The text describes Sai as the "illuminator of my speech" and the "capable lamp of knowledge" that destroys the darkness of ignorance. Because of his faith in the compassionate Lord, the author states that he felt no strain and his mind's wavering was stilled, reinforcing the idea presented throughout this chapter that he is just a vessel for Sai's work.
