Chapter 45 mentions that although Sai's physical form is gone, a 'literary form' remains. What is this literary form and what is its purpose?

According to Chapter 45, the "literary form" that remains after Sai Baba's physical incarnation has ended is the Shri Sai Satcharitra itself. The text explicitly states that while the physical form vanished once the work of the incarnation was complete, "this book, His literary form, will provide remembrance at every step." The purpose of this literary form, as explained in the chapter, is to serve as a constant source of remembrance and spiritual connection. The chapter further elaborates that listening to these stories allows the mind to attain a unique and indescribable peace through deep concentration, thereby continuing Sai's spiritual guidance.
