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

Chapter 52 explains that the book, referred to as "Sai Leela," was written to remember the experiences that Sai Baba gave to His devotees during His lifetime. The text highlights that Sai himself chose Hemadpant to write this true life story, holding his hand and guiding him despite Hemadpant feeling he was devoid of specialized knowledge. It's also mentioned that some of the fame and stories within the book were narrated by Sai with His own mouth for the disciples to hear, and the inspiration to compile it came after He departed to His own abode.
