How does the beginning of Chapter 53 illustrate the theme of divine will versus human intention?

The introductory part of Chapter 53 powerfully illustrates the theme of divine will superseding human plans. It begins by noting Hemadpant's unfulfilled promise to write the summary, but immediately clarifies that this was not his failure, stating, "Nothing happens by one's own will; Baba’s will is more powerful." The sudden passing of Hemadpant is presented as the ultimate proof of this principle. This theme is further reinforced by the new author's approach to completing the work. He feels completely incapable and surrenders his ego, praying for the Guru's grace and stating that Sai himself will be the one to write the summary through him. Thus, the very completion of the book is framed as an act of divine intervention rather than mere human effort.
