How does the author of the Sai Satcharita describe his role and inspiration for writing the book in Chapter 49?

In Chapter 49, the author expresses profound humility, stating that he is merely a vehicle for Sai's grace. He acknowledges that without Sai's direct inspiration, the work would be dry and lifeless. The text mentions, "He gives the remembrance of His own stories to complete this book." The author feels that the merciful Sainath entered his mind to get His own book written, thereby fulfilling the author's desires as well. He believes Sai himself is the true composer and writer, who provides timely remembrance if the author forgets the narrative, and even manifests stories unexpectedly, compelling him to pick up the pen, as detailed throughout Chapter 49.
