According to the source material, why was Hemadpant's promised summary for the book never completed by him?

According to Chapter 53, the primary reason Hemadpant did not complete the promised summary was his sudden and unexpected death. The chapter initially posits that forgetfulness could have been the cause but quickly dismisses this idea. It states definitively, "Nothing happens by one's own will; Baba’s will is more powerful." Hemadpant's passing left everyone grieved and uncertain about how to proceed with the conclusion of the book. This illustrates a key message of the chapter: human plans and promises are subordinate to the will of the Sadguru, Sai Baba, which governs all outcomes.
