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

According to Chapter 39, Chand Patil was the instrumental figure through whom Sai Baba came to Shirdi. The chapter describes him as a meritorious man who first found the "treasure" that was Sai, thereby enabling others to receive His Darshan. The text alludes to the story of how Chand Patil lost his horse, met Sai, was offered a smoke from the chillum, and subsequently found his horse. The direct reason for the journey to Shirdi, as mentioned in this chapter, was the marriage of Chand Patil's nephew, which was arranged in Shirdi. Sai Baba accompanied the wedding party from Dhupkheda to the bride's village. While Chand Patil is presented as the instrument, the chapter clarifies that Sai's incarnation and arrival were ultimately of his own accord for the upliftment of devotees.
