What does Chapter 12 suggest is the fundamental requirement for someone to have the good fortune of visiting Shirdi?

Chapter 12 reveals that a visit to Shirdi is not a matter of simple travel but a result of spiritual readiness. The text illustrates this through the story of an orthodox Agnihotri named Mule, who came to Shirdi "due to the strength of his past merits." It makes a very direct statement that without having this accumulated merit in one's possession, no one can stay in Shirdi for even a moment. This implies that the opportunity to be in the presence of a Sadguru like Sai is a rare and fortunate event, destined by one's past actions and spiritual destiny.
