Can you summarize the events leading to Sai Baba's arrival in Shirdi as recounted in Chapter 39?

Chapter 39 provides a concise summary of Sai Baba's journey to Shirdi. It states that Sai first appeared in the Nizam State, where he was found under a mango tree by a man named Chand Patil. This meeting occurred after Chand Patil had lost his horse. Subsequently, a wedding was arranged for Chand Patil's nephew with a bride from Shirdi. Sai Baba arrived in Shirdi unexpectedly along with this wedding party from Dhupkheda, an event the chapter frames as being ultimately orchestrated by Sai himself for the benefit of his future devotees.
