Can you explain the incident mentioned where Baba seemed to die for three days and then came back to life?

The provided text from Chapter 44 references a remarkable event that occurred 32 years before Sai Baba's final passing. In this earlier incident, Baba once drew his life force into the crown of his head for a period of three days. To onlookers, it appeared as if he had died, as the cessation of his breath made it seem impossible for him to rise again. This led to discussions about performing his final rites. However, the text states that Baba was 'extremely alert within' during this time. After the three days had passed, he suddenly returned to his body, dispelling the anxiety of his devotees. This event is mentioned in the context of his final passing to explain why people were initially doubtful whether he was truly gone or in a similar state of deep Samadhi.
