Chapter 12 mentions the beginning of a story. Who is the person being introduced, and what are the circumstances of their arrival in Shirdi?

Towards the end of the chapter, the narrative sets the stage for what it calls a "very delightful story" that illustrates the greatness of the Guru. It introduces a man from the holy city of Nashik, who is described as a ritualistic, orthodox Agnihotri (a keeper of the sacred fire) with the surname 'Mule'. According to Chapter 12, his arrival in Shirdi was not a simple coincidence but occurred due to the "strength of his past merits." The text emphasizes the significance of this, stating that without such accumulated merit, no one can stay in Shirdi for even a single moment.
