What specific events leading up to Sai Baba's final moments are promised to be narrated in Chapter 43?

Chapter 43 serves as an introduction that outlines several key events surrounding Sai Baba's Mahasamadhi. The narration promises to tell how, as death drew near, Sai listened to the Ramayana for his benefit, having it read to him by a Brahmin. It also states that it will explain how the planning for his Samadhi, or tomb, occurred and will detail the 'unseen fall of the brick' which was a precursor to this planning. Furthermore, this chapter from the Shri Sai Satcharitra sets the stage to recount a past incident where Baba appeared dead for three days before returning to his body, an event that left his followers astounded. These stories are presented as parts of a larger, purifying narrative.
