What is the purpose and significance of the "Sai Leela" book as described in Chapter 52?

Chapter 52 explains that the book "Sai Leela," also referred to as the Satcharitra, was written to remember the experiences Sai Baba gave to His devotees while He was in his physical body. It is described as supremely holy, containing the stories of His true character. The chapter emphasizes that reading this life story provides enlightenment for both this world and the next. It is also mentioned that Sai Baba himself inspired the book after His departure and that listening to the Satcharitra after taking darshan of the Samadhi can calm the three types of afflictions.
