According to the final chapter, what was Hemadpant's role in writing the Sai Satcharitra and what was the book's intended purpose?

Chapter 52 explains that Sai Baba himself chose Hemadpant to write his true life story, holding his hand through the process despite Hemadpant being devoid of specialized knowledge or learning. The inspiration for the book came after Sai's departure, though Sai had narrated some of His own fame for his disciples to hear. The purpose of this book, referred to as "Sai Leela," is to remember the experiences Sai gave to His devotees, to provide enlightenment for this world and the next, and to serve as a written record of His fame for the salvation of those who dedicate themselves to His devotion.
