According to Chapter 52, how did the Sai Satcharitra come to be written and who was chosen for the task?

Chapter 52 provides a retrospective look at the creation of the book, referred to as "Sai Leela." It states the book was written to remember the experiences Sai Baba gave to His devotees while He was in His body. The chapter emphasizes that Sai Baba Himself chose Hemadpant for this task, despite Hemadpant feeling he was devoid of specialized knowledge and learning. It is described that Sai Baba held his hand and caused this true life story to be written. The inspiration for the book reportedly came after Sai Baba departed to His own abode, drawing from the profound stories He used to narrate to his disciples.
