Why does the narrative in Chapter 2 pause to explain the origin of the name 'Hemadpant'?

The narrative pauses to explain the origin of the name "Hemadpant" primarily to satisfy the reader's curiosity and fulfill a promise made earlier. As explained in Chapter 2, the author acknowledges that the phrase "Composed by the devotee Hemadpant" appears at the end of every chapter, which would naturally make readers wonder about the identity of this person. The author mentions that he had promised at the end of the first chapter to tell this story. Therefore, he presents this explanation as a "sub-story within the story," considering it an inspiration from Sai to clarify the name's origin before continuing with the main sequence of Sai's life story.
