Why did the author decide to tell the story of how he got the name 'Hemadpant' in the middle of the book?

The author explains his reasoning for this narrative diversion in Chapter 2. Upon remembering Sai Baba's words, "Do not engage in dualistic explanations," he was reminded of a promise he made to his listeners at the end of the first chapter. He anticipated that readers would naturally become curious about the identity of "Hemadpant," whose name appears at the end of every chapter. To satisfy this curiosity and explain the origin and appropriateness of the name, he decided to insert this sub-story. As he notes in Chapter 2, he felt that this digression was also an inspiration from Sai Baba himself, after which the main life story would continue.
