The author seems to downplay his own role in writing the Satcharita in chapter 30. What does he say about Sai's involvement in the book's creation?

In Chapter 30, the author expresses deep humility regarding his part in writing the Sri Sai Satcharita. He questions his own abilities, asking, "what qualification do I have? Who takes up this task upon themselves?" He firmly believes that Sai is the true author and that he is merely an instrument. The text says, "He whose work it is, He Himself gets it accomplished. What burden is there on me then?" The author describes Sai as the "illuminator of my speech" and a "capable lamp of knowledge" who dispels the darkness of ignorance. This complete faith in Sai's grace is what stilled his wavering mind and allowed the sacred work to be completed.
