According to the text, why did Hemadpant not complete the Shri Sai Satcharitra, and what details does Chapter 53 provide about his character and work habits?

Chapter 53 explains that Hemadpant did not complete the Shri Sai Satcharitra because he suddenly passed away, leaving his promise to write a concluding summary unfulfilled. This chapter provides insight into his character, describing him as a 'jewel among poets' whose words were full of divine blessing. It also highlights his unique work habits, noting that he was very frugal and 'never let a scrap of paper go to waste.' He would write chapters on these scraps and give them directly to the printer. The text suggests this was born from a noble intent to have even these 'poor, lifeless scraps of paper' redeemed through service to Baba.
