Can you describe the incident mentioned in Chapter 43 where Sai Baba was presumed dead but later returned to his body?

Yes, Chapter 43 recounts a specific past event to illustrate Baba's extraordinary powers. It describes a time when Baba raised his life breath to the crown of his head, or Brahmarandhra, and remained in that state for three full days. His followers, with "certain minds," misinterpreted this deep state of Samadhi as death itself and began making preparations for the final rites. To their complete astonishment, Baba suddenly returned to his body, startling everyone. The chapter promises to provide a full account of how this happened, highlighting the incomprehensible nature of a yogi's control over life and death.
