Can you explain the context behind the author being called 'Hemadpant' and why he decided to tell that story?

The author, who is credited at the end of each chapter as "the devotee Hemadpant," explains in Chapter 2 that this naming naturally raises curiosity among listeners. He recalls a promise made at the end of the first chapter to narrate the story of how he received this name. He considers it a sub-story within the main narrative and feels it is an appropriate time to tell it, guided by Sai's inspiration. The purpose is to satisfy the reader's curiosity about the identity of "Pant" before continuing with the main sequence of Sai Baba's life story.
