How does Chapter 45 describe the continuing presence and influence of Sai Baba even after his physical incarnation has ended?

Even though Sai Baba's physical form has vanished, Chapter 45 explains that his presence and influence endure through the Shri Sai Satcharitra itself. The text explicitly states that this book serves as His 'literary form,' providing remembrance of him at every step. The chapter further elaborates that listening to the stories within the Satcharitra has a profound effect, leading the mind to a state of concentration that results in a unique and indescribable peace. This literary form, referred to as a 'speech-sacrifice' or Vag-yagna, ensures that Sai's work continues and his memory remains vivid for devotees.
