Chapter 43 mentions a past event where people mistakenly thought Sai Baba had died. Can you describe this incident based on the chapter's summary?

Yes, Chapter 43 alludes to a significant past event that it promises to narrate in more detail. According to the chapter's preview, there was an instance where Sai Baba had raised his life breath to the crown of his head, or Brahmarandhra, and remained in this state for three full days. This led people with 'certain minds' to believe that this was not a state of Samadhi but death itself. As a result, they began preparations for his final rites. Chapter 43 highlights the shock and surprise that followed when Baba suddenly returned to his body, startling everyone in their hearts.
