How does the author of the Shri Sai Satcharita describe his process of writing the book and Sai Baba's role in its creation?

The author portrays himself as a mere instrument for Sai Baba's divine will, attributing the creation of the Satcharita entirely to Sai. In Chapter 49, he explains that Sai Baba is the true composer and writer. The author states that if he ever feels lazy or forgets a narrative, Sai provides the remembrance at precisely the right time. He feels compelled to write, noting that a story can manifest so unexpectedly that his own will doesn't prevail and he must take up his pen. He concludes that the merciful Sainath entered his mind and had His own book written, thus fulfilling the author's desires and allowing these unfathomable stories to be shared with devotees.
