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

Chapter 52 of the Sai Satcharitra explains that the book, referred to as "Sai Leela," was written to remember the experiences that Sai Baba gave to His devotees while He was in His physical body. It is described as a supremely holy text containing stories of His true character. The chapter highlights that Sai Baba Himself chose Hemadpant to be the author, specifically noting that Hemadpant was devoid of specialized knowledge and learning. Sai held his hand and caused this true life story to be written, with some inspiration for the book arising after Sai had departed to His own abode.
