According to Chapter 52, why was the Sai Satcharitra written and who was chosen for this task?

Chapter 52 explains that the book, referred to as "Sai Leela," was written to remember the experiences Sai Baba gave to His devotees while He was in His body. The inspiration for the book came after He departed, drawing upon the stories He Himself had narrated. As detailed in Chapter 52, Sai Baba chose Hemadpant for this sacred task. It is specifically mentioned that Hemadpant was devoid of specialized knowledge and learning, but Baba Himself held his hand and caused this true life story to be written, making him the instrument for recording these divine plays for the benefit of all disciples.
