Following Sai Baba's physical departure, what role does the Shri Sai Satcharitra play according to the teachings in Chapter 45?

According to Chapter 45, even though Sai Baba's physical form has vanished, his legacy and presence endure through the Shri Sai Satcharitra, which is described as His "literary form." The chapter explains that when the work of the incarnation was complete, the physical body disappeared, but this book will provide remembrance of Him at every step. Furthermore, it is stated that listening to the stories within the Satcharitra with a concentrated mind brings a unique and indescribable peace. Therefore, the book serves as a direct conduit to His memory and a means for devotees to perform a supremely holy act.
