According to the provided text, what role did Chand Patil play in Sai Baba's arrival in Shirdi, and what is the deeper meaning behind this event?

Chapter 39 explains that a meritorious man named Chand Patil was the first to find Sai Baba. The chapter recounts that Sai came to Shirdi with the wedding party of Chand Patil's nephew. However, the text emphasizes that this was not a coincidence and that 'Chand Patil was merely an instrument.' The deeper meaning, as stated in Chapter 39, is that Sai took this incarnation and came to Shirdi 'of his own accord' out of a 'great concern for the upliftment of his devotees,' making the human events a vehicle for a divine purpose.
