Why wasn't the summary of the Shri Sai Satcharitra written by the original author, Hemadpant, as he had promised?

According to Chapter 53, the original author, Hemadpant (Dabholkar), had indeed promised to provide a summary to conclude the book. However, he was unable to fulfill this promise because he passed away suddenly, leaving everyone grieved. The chapter explains that while the general rule is for an author to complete their own work, this situation was an exception, highlighting that Baba's will is more powerful than human plans. Hemadpant's son, Gajanan, later provided his father's vast records, which were written on scraps of paper, so the work could be completed by another.
