What specific events leading up to Sai Baba's final departure are outlined in Chapter 43?

Chapter 43 provides a preview of the events surrounding Sai Baba's final moments. It states that the narration will tell how, as death drew near, Baba listened to the Ramayana for his own spiritual benefit, having it read to him by a Brahmin. Furthermore, the chapter promises to explain how the planning for his Samadhi, or tomb, occurred. A key part of this planning, as mentioned in the text, was the mysterious 'fall of the brick'.
