Chapter 43 mentions a past event where people mistakenly thought Baba had died. What details does the introduction provide about this incident?

The introduction in Chapter 43 previews a story about a time before Sai Baba's final departure when he was thought to have died. The text explains that Baba had raised his life breath to the crown of his head, or Brahmarandhra, for three days. Due to this, people with certain mindsets concluded it was not a state of Samadhi but death itself. As a result, they began making preparations for his final rites. As Chapter 43 recounts, everyone was startled when Baba suddenly returned to his body. The chapter promises to tell the full story of this startling event.
