For what reason does the author pause the main narrative to tell the story of how he was named 'Hemadpant'?

The author explains the inclusion of his naming story as a way to fulfill a promise and satisfy the reader's curiosity. As mentioned in Chapter 2, he had promised in the previous chapter to explain how he received the name "Hemadpant." The author acknowledges that readers would naturally wonder about the identity of "the devotee Hemadpant" who is credited at the end of each chapter. He states that this doubt "naturally arises," and telling this "sub-story within the story" is intended to satisfy that curiosity. The author also attributes this decision to divine will, noting, "this too is Sai’s inspiration." He asks the listeners to pay full attention before the main sequence of Sai's life story continues.
