How is the story of Sai Baba's arrival with Chand Patil's wedding party framed within the narrative of Chapter 39?

In Chapter 39, the story of Sai Baba's arrival is presented as a key event, but its context is carefully framed. The narrative recounts that Sai appeared in the Nizam State and later came to Shirdi with the wedding party for Chand Patil's nephew. The chapter briefly alludes to the prior events of how Chand Patil lost his horse and met Sai. However, it quickly pivots to a deeper spiritual interpretation, stating that this full story was told before and that Chand Patil was merely an instrument. The main point emphasized in this chapter is that Sai came to Shirdi of his own accord out of his great love for his devotees.
