According to Chapter 49, what is the author's perspective on his role in writing the Sai Satcharita?

In Chapter 49 of the Sai Satcharita, the author presents a deeply humble view of his role. He explains that he did not write the book of his own accord but was prompted by Sai Baba to start the Satcharita for the benefit of other devotees and for his own self-interest. The text emphasizes that Sai is the true composer and writer, and the author is merely an instrument. As stated in this chapter, if the author ever forgets the narrative, Sai provides the remembrance at the perfect moment, and without this divine inspiration, the work would be completely dry and lifeless. The author feels that the merciful Sainath entered his mind and got His own book written.
