Elaborate on the circumstances of Sai Baba's reappearance in Shirdi as detailed in the narrative involving Chand Patil.

Sai Baba's return to Shirdi, after a period of being hidden, is directly tied to the story of Chand Patil. As Chapter 5 explains, Baba was 'found' like a hidden 'gem' by Patil, the headman of Dhup village. This meeting was orchestrated by Baba's divine play, where he first helped Patil find his lost mare. He then revealed his saintly powers by miraculously producing fire and water to prepare his chillum. This convinced Patil of his divinity, and Baba subsequently stayed at Patil's house for some time. The eventual return to Shirdi occurred when Baba accompanied Chand Patil's family wedding procession, which was traveling to Shirdi for the marriage of Patil's wife's nephew.
