According to Chapter 49, what was the author's role in writing the Sai Satcharitra, and how was Sai Baba involved?

Chapter 49 explains that the author, Hemadpant, did not write the book on his own volition but was prompted and guided by Sai Baba. The text states, "He prompted me to start this Satcharita." The author clarifies that Sai Baba is both the composer and the writer, and without His inspiration, the work would be dry. As mentioned in Chapter 49, if the author ever forgot the narrative, Sai would give him "the remembrance at the right time." The author describes himself as a mere instrument, stating that the merciful Sainath entered his mind and "got His own book written," thereby fulfilling the author's desires as well.
