What are the main topics outlined in the introduction of Chapter 43 of the Shri Sai Satcharitra?

Chapter 43 continues the narrative from the previous chapter concerning the passing of Saint Sai, promising to complete the story. As outlined in the chapter's introduction, the author Hemad expresses his devotion and states that the text will cover several key events. These include how Sai listened to the Ramayana as death neared, the planning for his Samadhi (tomb), and the significance of the 'fall of the brick.' Chapter 43 also mentions it will recount a past incident where Baba was presumed dead for three days after raising his life breath to the crown of his head, only to suddenly return to his body, startling everyone.
