According to the text, what was Chand Patil's role in Sai Baba's arrival in Shirdi, and what is the deeper reason given for Sai's presence there?

Chapter 39 explains that Sai Baba unexpectedly arrived in Shirdi with the wedding party of Chand Patil's nephew from Dhupkheda. Chand Patil, a meritorious man, was the first to find this "treasure" (Sai). However, the text clarifies that Chand Patil was merely an instrument in this event. The true reason for Sai's incarnation and arrival in Shirdi, as stated in this chapter, was his own profound concern for the upliftment of his devotees. He came of his own accord specifically to help the simple, faithful, fallen, and poor who lacked other spiritual means.
