Can you explain the incident mentioned in Chapter 43 where people mistakenly thought Sai Baba had already died once before?

Yes, Chapter 43 recounts a past event where people wrongly concluded that Sai Baba had passed away. According to the text, Baba had raised his life breath to the crown of his head (Brahmarandhra) and remained in that state for three full days. People with "certain minds" interpreted this not as a state of Samadhi but as death itself. Consequently, preparations for his final rites were actually initiated. However, as described in this chapter, everyone was startled when Baba suddenly returned to his body, proving their assumptions incorrect. This story is included to provide context for his final, actual departure.
