Why does the narrative interrupt Sai's life story to talk about the author's nickname, 'Hemadpant'? It seems like a self-indulgent distraction from the main subject.

The text acknowledges this digression and justifies it as being divinely inspired. As explained in Chapter 2, the author remembers his promise to explain the origin of the name "Hemadpant" and frames the fulfillment of this promise as more than a mere sidetrack. The narrative states, "Listening to this sub-story within the story will reveal its appropriateness. Curiosity will be satisfied; this too is Sai’s inspiration." The book anticipates that readers will naturally become curious about the name "Hemadpant" appearing at the end of every chapter. Addressing this curiosity is presented as a necessary part of the narrative's structure, willed by Sai himself, before the main life story continues.
