I keep seeing the name 'Hemadpant' in the book. Who is he and why is the author pausing the main story to talk about him?

Hemadpant is the author of the 'Sai Leela' book, and his name is mentioned at the end of every chapter. As explained in Chapter 2, the author acknowledges that this naturally raises curiosity among listeners about who 'Pant' is. He pauses the main life story of Sai to tell the sub-story of how he received this name, fulfilling a promise made at the end of the first chapter. The author sees this digression as an inspiration from Sai and a way to satisfy the reader's curiosity before continuing with the sequence of Sai's life story.
