Chapter 43 mentions an event where people thought Sai Baba had died, but he returned. Could you elaborate on this incident as described in the chapter?

Chapter 43 provides a preview of a remarkable story concerning Sai Baba's control over his own life force. The chapter explains that on one occasion, Baba raised his life breath to the crown of his head, a state known as Brahmarandhra, and remained in this state for three consecutive days. People, observing his motionless body, concluded that it was not a state of Samadhi but death itself. Consequently, they began making preparations for his final rites. As Chapter 43 recounts, these preparations were cut short when, to everyone's astonishment, Baba suddenly returned to his body, startling all who were present.
