Can you describe Hemadpant's writing habits and what became of his notes for the final chapter?

Chapter 53 reveals that Hemadpant had a very frugal and distinctive writing process. He was known for never letting a scrap of paper go to waste, to the point where he would write chapters on these scraps and then give those very same pieces to the printer. This was driven by a sense of compassion for the paper itself, with the noble intent that even these "lifeless scraps" could be redeemed through service to Sai Baba. His final chapter was written in the same manner, on various scraps of paper. After his passing, many people, including his son Gajananrao, searched through these notes, but the promised summary could not be found within them.
