Can you tell me about the person from Nashik who is introduced in Chapter 12 and the circumstances of his arrival in Shirdi?

Chapter 12 introduces the story of a ritualistic and orthodox Agnihotri (a keeper of the sacred fire) from the holy city of Nashik, whose surname was 'Mule'. His arrival in Shirdi is attributed to the "strength of his past merits," as the chapter suggests that one cannot stay in Shirdi for even a moment without such a foundation. The narrative is set up as a delightful story illustrating the greatness of the Guru. It is mentioned that his original intention for the journey was different, but a fortunate coincidence led him to Shirdi, where he ultimately gained the benefit of seeing his own Guru.
