Why didn't Hemadpant, the original author of the Sai Satcharitra, write the concluding summary himself?

According to Chapter 53, the original author, Hemadpant (also known as Dabholkar), had promised to review the book and provide a summary to complete it. However, this did not come to pass because he passed away suddenly, leaving his work unfinished and grieving the hearts of many. The chapter emphasizes that while it's a general rule for the original author to complete their own book, there are exceptions. It ultimately attributes this turn of events to a will more powerful than one's own, suggesting that it was Baba's will that prevailed over Hemadpant's intentions.
