Why didn't the original author, Hemadpant, finish the Shri Sai Satcharitra with the summary he promised?

According to Chapter 53, the original author, Panta Hemad (Dabholkar), had indeed promised to provide a summary to complete the book. However, this did not happen because he suddenly passed away, leaving his work unfinished. The text explains that while it is a general rule for the author who begins a book to be the one to complete it, there are exceptions, and this was one such case. It is noted that "Nothing happens by one's own will; Baba’s will is more powerful." Even after searching through Hemadpant's records, the promised summary could not be found, leaving the task to a successor.
