According to Chapter 45, how is Sai Baba's presence sustained after his physical body vanished, and what is the role of the Satcharitra in this?

Chapter 45 addresses the departure of Sai Baba's physical form by explaining how His presence is perpetuated. The chapter states that before He "brought His incarnation to an end," Sai established "His own form in the hearts of devotees through meditation." More significantly, it posits that the Satcharitra itself serves as His enduring presence. The text from Chapter 45 declares that while the physical form vanished, "this book, His literary form, will provide remembrance at every step." Thus, the Satcharitra is not merely a biography but is framed as the living, literary embodiment of Sai, through which devotees can experience His guidance, attain peace, and feel His presence.
