How does Chapter 53 use the story of the unwritten summary to illustrate a central theme about divine will?

Chapter 53 uses the circumstances surrounding the book's conclusion to powerfully illustrate the theme of divine will over human intention. It begins by noting that the original author, Hemadpant, promised a summary but died before he could write it. The chapter explicitly states, "Nothing happens by one's own will; Baba’s will is more powerful." This idea is reinforced by the new author's feelings of inadequacy and his complete surrender to a higher power. He concludes that "Sai, the breaker of obstacles (Vakratunda), will be the one to write this summary. His glory is immense; my mouth is merely an instrument." This narrative, as presented in chapter 53, frames the entire creation of the Satcharitra's conclusion not as a human act, but as an act of Sai's grace.
