According to Chapter 49, how does the author of the Sai Satcharitra view his own role in creating the book?

In Chapter 49 of the Sai Satcharitra, the author presents himself as merely an instrument for a higher power. He explicitly states that Sai Baba himself is the true composer and writer of the book. The author feels that without Sai's divine inspiration, the text would be lifeless and dry. He describes how, even if he feels lazy or forgets the narrative, Sai gives him the remembrance at the right time, compelling him to pick up the pen. The text concludes that the merciful Sainath entered the author's mind, got His own book written, and fulfilled the author's desires in the process, emphasizing that he was prompted by Sai to start the Satcharita for his own self-interest and for the benefit of other devotees.
