Why wasn't the concluding summary of the Shri Sai Satcharitra written by the original author, Hemadpant?

According to Chapter 53, the original author, Panta Hemad (Dabholkar), had promised to provide a summary to complete the book. However, he suddenly passed away before this could be accomplished, which grieved everyone. The text explains that while it is the general rule for an author to complete their own book, this was an exception, emphasizing that nothing happens by one's own will and that Baba’s will is more powerful. This unforeseen event left the summary unwritten by its intended author, necessitating another to take up the task.
