Why did the author feel it was necessary to tell the story of how he was named 'Hemadpant'?

The author felt compelled to explain the origin of his name "Hemadpant" for several key reasons, as detailed in Chapter 2. Firstly, he had made a promise to his listeners at the end of the previous chapter to tell this story, and he intended to fulfill that commitment. Secondly, he recognized that since the name "Hemadpant" appears at the end of every chapter as the composer, it would naturally spark curiosity in the readers' minds. He wished to satisfy this curiosity directly. Lastly, he viewed the telling of this sub-story not as a mere digression, but as another instance of Sai's own inspiration, and an appropriate prelude before continuing the main sequence of Sai Baba's life story.
