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

Chapter 43 serves as a continuation of the narrative concerning the passing of Saint Sai. The author, Hemad, outlines several key events, including how Sai listened to the Ramayana being read by a Brahmin as his end drew near and the planning for his Samadhi. The chapter also recounts a remarkable prior incident where Baba seemed to have passed away for three days, causing followers to prepare for final rites, only for him to return to his body, startling everyone. As described in Chapter 43, the text also explores the philosophical transition of Sai from a manifest, physical form to an unmanifest and omnipresent state, becoming eternally whole and the soul of all.
