According to Chapter 52, how was the Sai Satcharitra written and for what purpose?

Chapter 52 explains that the Sai Satcharitra, also called "Sai Leela," was written to preserve the memory of the experiences Sai Baba gave to His devotees. It states that Baba Himself chose Hemadpant, who described himself as being without specialized knowledge, and metaphorically held his hand to get this true life story written. While Baba narrated some of his own fame during his lifetime, the inspiration to compile the book came after He departed. The ultimate purpose, as mentioned in Chapter 52, was for the salvation of His devotees, providing a sacred text that offers enlightenment for this world and the next.
