Chapter 12 mentions a story about someone from Nashik. Who was he and why was his visit to Shirdi significant?

Chapter 12 introduces the story of an orthodox, ritualistic Agnihotri (a keeper of the sacred fire) from Nashik, with the surname 'Mule'. His visit is presented as a "strange thing" that happened due to a stroke of good fortune and the strength of his past merits. The chapter explains that his initial intention for the journey was different, but a coincidence led him to Shirdi, where he gained an unexpected benefit. The text from Chapter 12 frames this narrative as a delightful story that illustrates the greatness of the Guru. It also notes that without past merit, one cannot stay in Shirdi for even a moment.
