According to Chapter 39, what was Chand Patil's specific role in Sai Baba's arrival in Shirdi?

Chapter 39 explains that Chand Patil was a meritorious man who was the first to find the "treasure" that was Sai Baba. Their meeting occurred after Patil's horse was lost, and the chapter mentions how Sai helped him find the horse and made him smoke the chillum. Later, Sai Baba arrived in Shirdi along with the wedding party for Chand Patil's nephew. However, the chapter clarifies that Chand Patil was merely an instrument in this process. The text states that Sai Baba took this incarnation and came to Shirdi of his own accord, driven by a great concern for the upliftment of his devotees, especially the simple and faithful.
