Why wasn't the Shri Sai Satcharitra originally completed by its author, Hemadpant?

According to Chapter 53, the original author, Hemadpant, had fully intended to complete the Shri Sai Satcharitra by writing a concluding summary. He had even made a promise to do so. However, this plan was unfulfilled because he suddenly passed away, leaving his work unfinished and the hearts of devotees grieved. The chapter poignantly notes that this serves as an exception to the general rule that an author finishes their own book, emphasizing that ultimately, "Baba’s will is more powerful" than one's own intentions, and nothing happens without it. The task of completion therefore fell to another devotee.
