Chapter 39 mentions several key events related to Sai Baba's arrival. Can you reconstruct this sequence and explain the underlying divine purpose as described in the text?

Chapter 39 outlines the sequence of events leading to Sai Baba's presence in Shirdi. He first appeared in the Nizam State, where he was found by Chand Patil, who had lost his horse. After this encounter, Sai Baba traveled with the wedding party of Chand Patil's nephew to Shirdi. While these events seem circumstantial, the chapter emphasizes a deeper, divine plan. It clarifies that Chand Patil was "merely an instrument" and that Sai Baba's incarnation and arrival in Shirdi were self-motivated by his "great concern for the upliftment of his devotees," especially the poor and simple. This narrative frames his arrival not as a chance occurrence but as a deliberate act of compassion.
