According to Chapter 52, why was the book 'Sai Leela' written and who was chosen as the author?

The book 'Sai Leela,' or Sai Satcharitra, was written to preserve and remember the experiences Sai Baba gave to His devotees while He was in His physical body. Chapter 52 describes the book as a supremely holy text containing the stories of His true character. It is revealed that Sai Baba Himself chose Hemadpant to be the author, despite Hemadpant being devoid of specialized knowledge. The text states that Sai held Hemadpant's hand and caused this true life story to be written, with inspiration also coming from the profound stories Sai Himself narrated to His disciples.
