Why does the author pause the main narrative to discuss the origin of the name "Hemadpant"?

The author explains in Chapter 2 that he feels compelled to tell the story of how he received the name "Hemadpant" for a few key reasons. Firstly, he acknowledges that a doubt naturally arises in the reader's mind, as every chapter concludes with the line, "Composed by the devotee Hemadpant." He wants to satisfy the curiosity about who this "Pant" is. Secondly, he feels it is an appropriate time to share this sub-story, framing it as an inspiration from Sai himself. He promises the listeners that hearing this story will be satisfying and that afterward, the main sequence of Sai's life story will continue. This narrative detour serves to build a connection with the reader.
