Why does the author bring up the story of how he got the name 'Hemadpant'?

The author explains in Chapter 2 that he is addressing the origin of the name 'Hemadpant' to satisfy the natural curiosity of his listeners and readers. He notes that at the end of every chapter, the line "Composed by the devotee Hemadpant" appears, which would make people wonder about the identity of this person. He remembers his promise from the first chapter to tell this story and sees the impulse to do so as an inspiration from Sai Baba. By sharing this "sub-story within the story," he aims to explain the appropriateness of the name and provide a brief, interesting diversion before continuing with the main sequence of Sai Baba's life story.
