Can you describe the past incident mentioned in Chapter 43 where people mistakenly thought Sai Baba had died?

Certainly. Chapter 43 recounts a remarkable past event to illustrate Sai Baba's yogic power. In this incident, Baba raised his life breath to the crown of his head, a state known as Brahmarandhra, and remained in this state for three full days. People with 'certain minds', unable to comprehend this deep state of Samadhi, concluded that it was not a yogic trance but death itself. As a result, they began making preparations for his final rites. However, as Chapter 43 narrates, everyone was startled when Baba suddenly returned to his body, demonstrating the profound difference between a yogi's control over their life force and an ordinary passing.
