The text mentions Sai Baba had authority over death. What events or statements from the scripture support this claim?

Chapter 44 provides several pieces of evidence to support the claim that Sai Baba had authority over death. Firstly, it makes the direct philosophical statement, "He who has authority even over Time (Death); how can he suffer at its hands?" Secondly, it details a past incident where Baba consciously drew his life force into the crown of his head for three days, appearing dead before returning to his body, demonstrating control over his vital functions. Lastly, the manner of his final passing is presented as a deliberate act, where he chose the time after listening to the Ramayana for exactly two weeks, concluding his life on the day of Vijayadashami.
