I heard Chapter 12 introduces a new story. Who is the Agnihotri from Nashik, and what is the significance of his arrival in Shirdi?

Chapter 12 sets the stage for a new narrative by introducing a man named Mule, an orthodox and ritualistic Agnihotri (a keeper of the sacred fire) from the holy city of Nashik. The chapter explains that his arrival in Shirdi was not a random occurrence but happened 'due to the strength of his past merits.' The text emphasizes that without such merit, a person cannot stay in Shirdi for even a moment. It hints that his original intention for the journey was different from the outcome, but a fortunate coincidence led him to Shirdi, where he would gain a significant benefit and come into the sight of his own Guru. This story is presented as a delightful illustration of the greatness of the Guru.
