Why wasn't the Shri Sai Satcharitra finished by its original author, Hemadpant?

According to Chapter 53 of the Shri Sai Satcharitra, the original author, Hemadpant (also referred to as Panta Hemad or Annasaheb), had promised to conclude the book with a summary of its contents. However, he was unable to fulfill this promise because he passed away suddenly. The text explicitly states, "Hemad suddenly passed away, leaving everyone’s heart grieved." This unexpected event left the work incomplete, as no one knew about the summary or what to do next. The chapter clarifies that this was an exception to the general rule that the person who begins a book should be the one to complete it, emphasizing that Baba's will is more powerful than one's own.
