Chapter 43 mentions a past event where people mistakenly thought Baba had passed away. Can you describe what happened?

Indeed, Chapter 43 provides a preview of a remarkable past incident that demonstrated Sai Baba's yogic mastery. The text explains that on one occasion, Baba raised his "life breath to the crown of his head (Brahmarandhra)" and remained in that state for three consecutive days. As mentioned in Chapter 43, some observers misunderstood this profound yogic state of Samadhi, believing it to be actual death. They even began making preparations for his final rites. However, Baba then suddenly returned to his body, which startled everyone and revealed their misunderstanding of his spiritual capabilities.
