Why was the summary for the Shri Sai Satcharitra not written by the original author, Hemadpant?

According to Chapter 53, the original author, Hemadpant (Dabholkar), had promised to review the work and provide a summary to conclude the book. However, he was unable to fulfill this promise because he suddenly passed away. This event is presented as an exception to the general rule that the person who starts a book should be the one to complete it. The chapter emphasizes that this unexpected turn of events demonstrates a higher power at play, stating that "nothing happens by one's own will; Baba’s will is more powerful."
