According to Chapter 52, what was the purpose of writing the 'Sai Satcharitra' and who was chosen for this task?

As explained in Chapter 52, the book, also referred to as "Sai Leela," was written to remember the experiences Sai Baba gave to His devotees while He was in his physical body. The text is described as supremely holy, containing the stories of His true character. The chapter reveals that Sai Baba Himself chose Hemadpant for this task, despite him being devoid of specialized knowledge and learning. It is beautifully stated that Baba held Hemadpant's hand and caused this true life story to be written, with the inspiration for the book arising after Baba's departure.
