According to Chapter 52, why was the Sai Satcharitra written and who was chosen to be the author?

Chapter 52 of the Sai Satcharitra provides a retrospective on the book's creation, explaining that it was written to document and remember the experiences Sai Baba gave to His devotees while He was in His physical body. The text, referred to as "Sai Leela," is described as supremely holy. The chapter emphasizes that Sai Baba Himself initiated this work, choosing Hemadpant as the scribe. It is noted that Hemadpant considered himself to be without specialized knowledge, but Baba held his hand and guided him in writing this true life story. As detailed in Chapter 52, some of the stories were even narrated by Sai Baba Himself, and the inspiration for the book came after He took Mahasamadhi.
