What is the purpose of the book "Sai Leela" or "Satcharitra" as described in Chapter 52?

Chapter 52 explains that the book "Sai Leela," also known as the Satcharitra, was written to remember the experiences Sai Baba gave to His devotees while He was in His physical body. This supremely holy text, which contains stories of His true character, is meant to provide enlightenment for this world and the next. The chapter states that Sai Baba Himself inspired the book after His departure and that listening to this Satcharitra, especially after taking darshan of the Samadhi, can calm the three types of afflictions and dispel millions of sins.
