How does Chapter 53 explore the theme of human will versus divine will in the context of creating the Shri Sai Satcharitra?

Chapter 53 uses the incompletion of the book by its original author, Hemadpant, to powerfully illustrate the theme of divine will prevailing over human plans. The chapter notes that while the general rule is for an author to finish their own book, this case was an exception. It explicitly states, "Nothing happens by one's own will; Baba’s will is more powerful." Hemadpant's promise to write a summary was unfulfilled due to his sudden death, an event beyond his control. The new author, as shown in Chapter 53, reinforces this theme by surrendering his own ego, praying for grace, and declaring that Sai is the true author working through him as an instrument, thus framing the entire creation of the book as a manifestation of the Guru's will.
