After Sai Baba's physical departure, what does Chapter 45 identify as the continuing source of his presence and remembrance?

According to Chapter 45, even though Sai Baba's physical form vanished once the work of his incarnation was complete, his literary form—the Shri Sai Satcharitra—will provide remembrance for devotees at every step. The chapter describes this book as a 'speech-sacrifice' (Vag-yagna). It asserts that listening to these stories allows the mind to attain a unique and indescribable peace. Therefore, this sacred text is presented as the enduring form of Sai that continues to guide and bring solace to his followers.
