I heard about an incident where Sai Baba seemed to have died but then came back. Is that story mentioned in Chapter 43?

Yes, that remarkable event is referenced in Chapter 43 as a story to be told. The text mentions a past incident where Sai Baba raised his life breath to the crown of his head, or Brahmarandhra, for three consecutive days. During this time, some people, believing it was death rather than a state of Samadhi, began to make preparations for his final rites. As Chapter 43 recounts, these individuals were startled when Baba suddenly returned to his body. This event is highlighted to demonstrate his extraordinary yogic powers and the incomprehensible nature of his being, distinguishing him from ordinary mortals.
