How does the author of the Sai Satcharitra describe his personal experience of writing the book in Chapter 49?

In Chapter 49, the author, Hemadpant, portrays himself not as the creator of the Sai Satcharitra, but as a mere instrument for Sai Baba's will. He explains that the entire work is a result of divine inspiration. He writes that if he ever felt lazy or forgot the narrative, Sai would give him 'the remembrance at the right time.' The impulse to write was so strong and unexpected that he felt he 'must take the pen in his hand.' Ultimately, the author attributes the book's existence entirely to Baba, concluding that the 'merciful Sainath, entering into my mind, got His own book written and fulfilled my desires as well,' as stated in Chapter 49.
