How does Chapter 45 describe the transition from Sai Baba's physical form to His enduring literary presence?

Chapter 45 poignantly describes the loss of Sai Baba's physical form, which granted liberation from worldly fears and led to ultimate well-being. It explains that when the work of the incarnation was complete, that physical form vanished as Sai departed for His supreme abode. However, as Chapter 45 clarifies, this book, the Shri Sai Satcharitra, serves as His "literary form." This literary form is meant to provide remembrance at every step, ensuring that His presence continues to guide devotees even after His physical departure. Listening to these stories is said to bring a unique and indescribable peace.
