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

Chapter 43 continues the narrative of Sai Baba's passing, picking up where the previous chapter left off. The author, Hemad, expresses his devotion and states his intent to complete the story. The chapter provides a preview of its contents, mentioning how Baba listened to the Ramayana before his death, the planning for his Samadhi (tomb), and the symbolic 'fall of the brick'. It also alludes to a past event where Baba appeared to have died for three days before returning to his body, startling his devotees.
