Why does the author interrupt the main story to talk about how he was named 'Hemadpant'?

The author pauses the main narrative to address a curiosity that he anticipates in the reader. As mentioned in Chapter 2, the phrase "Composed by the devotee Hemadpant" appears at the end of every chapter, which naturally raises the question of who this person is. The author decides to tell the story of how he received this name to satisfy that curiosity, viewing the telling of this sub-story as an inspiration from Sai. He assures the listeners that after this short story about his naming ceremony is complete, the main sequence of Sai’s life story will continue.
