According to Chapter 52, why was the Sai Satcharitra written and who was chosen to author it?

Chapter 52 explains that the book, referred to as "Sai Leela," was created to remember the experiences Sai Baba gave to His devotees while He was in His physical body. It is described as a supremely holy text containing the stories of His true character. As mentioned in Chapter 52, Sai Baba chose Hemadpant to be the author, holding his hand and causing this true life story to be written, despite Hemadpant being "devoid of specialized knowledge and learning." This highlights that the creation of the book was an act of Sai's grace and inspiration, which came after He departed to His own abode.
