Chapter 43 mentions a past event where Baba seemed to have died but returned. Can you elaborate on what the chapter promises to narrate about this incident?

Chapter 43 provides a preview of a remarkable past incident that will be recounted in detail. The chapter states that on one occasion, Sai Baba raised his life breath to the crown of his head, or 'Brahmarandhra,' for three consecutive days. Because of this, some people mistakenly thought he had actually died rather than entered a state of Samadhi. Consequently, they began preparations for his final rites. As Chapter 43 explains, the story will detail how Baba then suddenly returned to his body, which startled everyone in their hearts.
