The text mentions Hemadpant wrote on scraps of paper. Can you explain his reasons and what became of the notes for the final chapter?

Chapter 53 explains that Hemadpant's habit of writing on scraps of paper stemmed from two main reasons. Firstly, he was frugal by nature and "never let a scrap of paper go to waste." Secondly, and more profoundly, he felt compassion for these "poor, lifeless scraps" and believed they could be redeemed by being used in the service of Sai Baba, the "Lion among Saints." This noble intent extended to the final chapter, which was also found written on such scraps. However, when his son Gajananrao researched these notes after his father's passing, it was discovered that the promised summary was not among them, which led to the need for a new author to complete the work.
