What is the purpose and significance of the book "Sai Leela" or "Satcharitra" 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. This text is considered supremely holy and contains the stories of his true character. As the chapter highlights, reading this life story provides enlightenment for both this world and the next. It is also mentioned that even though Hemadpant felt he lacked specialized knowledge, Sai Baba himself held his hand and caused this true life story to be written, with the inspiration for the book coming after Sai's departure.
