Can you elaborate on the incident mentioned in Chapter 43 where people mistakenly believed Sai Baba had died prior to his actual passing?

Chapter 43 recounts a remarkable past event where Sai Baba demonstrated his yogic power over life and death. The chapter describes how Baba once raised his life breath to the crown of his head (Brahmarandhra) and remained in that state for three consecutive days. Seeing his body motionless for so long, some people concluded it was not a state of Samadhi but actual death. As detailed in Chapter 43, they even began making preparations for the final rites. Their plans were abruptly halted when Baba suddenly returned to his body, which startled everyone and proved his mastery over his own physical form.
