How does the author of the Sai Satcharitra describe his own process and inspiration for writing the book in Chapter 49?

In Chapter 49, the author explains that the writing of the Satcharita was not his own doing but was prompted entirely by Sai Baba. He states that the merciful Sainath entered his mind to get His own book written. The author mentions that even if he tries to sit quietly, an unexpected story manifests, compelling him to take up the pen. He clarifies that Sai Himself is both the composer and the writer of these saintly stories, and without this divine inspiration, the work would be devoid of substance. He writes that if he ever forgets a narrative, Sai gives him the remembrance at the perfect time, thus fulfilling the author's desires while completing the book.
