Chapter 12 introduces a story about an Agnihotri from Nashik. Who is he, and why is his story presented as significant?

Chapter 12 sets the stage for a story about a ritualistic, orthodox Agnihotri (a keeper of the sacred fire) from Nashik, with the surname 'Mule'. His arrival in Shirdi is attributed to the strength of his past merits, without which, the text claims, no one can stay there for even a moment. The narrative introduces this as a "very delightful story" that is significant because it illustrates the greatness of the Guru. As Chapter 12 explains, the Agnihotri's original intention was different, but a fortunate coincidence led him to gain the benefit of Shirdi and see his own Guru, making the story a powerful example of love for a Guru's devotees.
