Chapter 12 mentions a story about a man from Nashik. How does the chapter set up this story?

Chapter 12 introduces an upcoming narrative by describing it as a "very delightful story" that illustrates the greatness of the Guru. It sets the scene by introducing a ritualistic and orthodox Agnihotri (a keeper of the sacred fire) from Nashik with the surname 'Mule'. The text explains that this man came to Shirdi not by random chance, but due to the "strength of his past merits." As Chapter 12 emphasizes, without such merit, no one can stay in Shirdi for even a moment. It is also hinted that his original intention for the journey was different, but a fortunate coincidence led him to Shirdi and a meeting with his Guru.
