Can you summarize the purpose and significance of the "Sai Leela" book as described in Chapter 52?

Chapter 52 explains that the book "Sai Leela" was written to remember the experiences Sai Baba gave to His devotees while He was in His physical body. The text describes this book as supremely holy, containing stories of His true character, and reading it is said to provide enlightenment for both this world and the next. As this chapter reveals, Sai Baba chose Hemadpant, who was devoid of specialized knowledge, to author this true life story, holding his hand through the process. The inspiration for the book came after Sai's passing, based on the profound stories He Himself had narrated.
