What are the main events and themes covered in Chapter 43 of the Shri Sai Satcharitra?

Chapter 43 of the Shri Sai Satcharitra continues the narrative of Sai Baba's passing from the previous chapter. The author, Hemad, explains that this chapter will complete the story. As detailed in the text, it covers several key events: how Sai listened to the Ramayana being read by a Brahmin as his death approached, the planning for his Samadhi, and the incident of the 'fall of the brick'. Chapter 43 also recounts a past event where Baba appeared to be dead for three days after raising his life breath, only to return to his body, startling his devotees. The chapter concludes by describing the grief of the villagers and reflecting on how Baba transitioned from a manifest, embodied form to an unmanifest, omnipresent state, achieving an imperishable existence.
