Can you describe the specific events leading up to Sai's passing that are outlined for discussion in Chapter 43?

In Chapter 43, the author provides a preview of the topics he will cover regarding Sai Baba's Mahasamadhi. He states that the narration will explain how, as death drew near, Sai listened to the Ramayana for his own benefit through the mouth of a Brahmin. The chapter promises to detail how the planning for the Samadhi (tomb) occurred, which was connected to an event known as the 'fall of the brick.' Furthermore, Chapter 43 sets out to tell the story of how Baba once raised his life breath for three days, was presumed dead, and then suddenly returned to his body, startling his followers. These planned narrations complete the story of his departure.
