Chapter 12 introduces a story about a man named Mule. What details does the chapter provide to set up this story?

To introduce an upcoming narrative, Chapter 12 sets the scene for what it calls a "very delightful story" that illustrates the Guru's greatness. It introduces a man from the holy city of Nashik, an orthodox and ritualistic Agnihotri (keeper of the sacred fire) with the surname 'Mule'. According to Chapter 12, his arrival in Shirdi was not a random event but occurred due to the "strength of his past merits," as the text claims no one can stay in Shirdi even for a moment without such merit. The chapter builds suspense by mentioning that his original intention was different from the outcome, and this fortunate coincidence led him to gain the benefit of Shirdi.
