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

In Chapter 49, the author humbly portrays himself as merely an instrument for a divine will. He explains that the merciful Sainath entered his mind and orchestrated the writing of His own book, thereby fulfilling the author's desires as well. The text reveals that Sai's intervention was direct; if the author ever felt lazy or forgot the narrative, Sai would provide the remembrance at the perfect moment. The author felt compelled to write, stating that a story would manifest so unexpectedly that he had to take up his pen, concluding that Sai Himself is the true composer and writer of the Satcharita.
