Based on Chapter 39, what were the circumstances of Chand Patil's first encounter with Sai and how did it lead to Sai's arrival in Shirdi?

Chapter 39 recounts that Sai Baba's arrival in Shirdi was facilitated by a meritorious man named Chand Patil. Sai first appeared under a mango tree in the Nizam State, where he was found by Chand Patil, who had lost his horse. The chapter alludes to the story of how Sai made him smoke a chillum and how Patil's horse was subsequently found. Later, a wedding was arranged for Chand Patil's nephew with a bride from Shirdi. Sai Baba accompanied the wedding party to Shirdi. However, as Chapter 39 clarifies, Chand Patil was merely an instrument; Sai came to Shirdi of his own accord out of a deep concern for the spiritual upliftment of his devotees.
