According to Chapter 45, how does Sai Baba's presence continue to guide devotees even after his physical departure?

Chapter 45 explains that although Sai Baba's physical form is now lost, His presence endures through spiritual means and His teachings. The chapter states that before bringing His incarnation to an end, Sai established His own form in the hearts of devotees through meditation. As further detailed in Chapter 45, this very book, the Shri Sai Satcharitra, serves as His literary form. It is intended to provide remembrance at every step, and listening to its stories with a concentrated mind is described as a holy act that brings a unique and indescribable peace.
