Can you elaborate on the incident mentioned in Chapter 43 where Sai Baba was thought to be dead but then returned to life?

Chapter 43 provides a preview of a startling past event that illustrates Sai Baba's incomprehensible power. In this incident, Sai raised his life breath to the crown of his head, or Brahmarandhra, and remained in that state for three full days. As described in Chapter 43, those present were certain that this was not a state of Samadhi but death itself and consequently began preparations for the final rites. To their utter astonishment, Baba suddenly returned to his body, which startled everyone in their hearts. This story highlights the mysterious nature of a saint's control over life and death.
