How does Chapter 45 contrast the finality of Sai's physical departure with the enduring nature of his spiritual legacy?

Chapter 45 masterfully contrasts the physical and spiritual realities of Sai Baba's legacy. It first describes the end of his incarnation as a profound "state of Yoga" beyond comprehension, where the physical form vanished. This loss is deeply felt, as that form was a source of bliss and courage. However, the chapter immediately pivots to the enduring legacy, stating that this book, the Shri Sai Satcharitra, now serves as His "literary form." As Chapter 45 explains, this literary work, described as a "speech-sacrifice (Vag-yagna)," ensures His remembrance. Listening to these stories becomes a supremely holy act that provides a unique peace, thus transcending the physical absence.
