Can you detail the circumstances of Sai Baba's arrival in Shirdi as described in Chapter 39, including the role of Chand Patil?

As recorded in Chapter 39, Sai Baba first appeared in the Nizam State under a mango tree and later arrived in Shirdi quite unexpectedly with a wedding party from Dhupkheda. This came about because a meritorious man named Chand Patil, who was the first to find this 'treasure' (Sai), had a nephew whose marriage was arranged in Shirdi. The wedding party traveled to the bride's village, bringing Sai with them. The chapter clarifies that Chand Patil was merely an instrument, suggesting that Sai came to Shirdi of his own accord for the greater purpose of uplifting his devotees.
