Why does the author of the 'Sai Leela' book pause the main story to explain how he was named 'Hemadpant'?

The author pauses the main narrative to address a curiosity that he anticipates in the reader's mind. As he explains 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. He feels it is appropriate to tell this 'sub-story within the story' to satisfy the listeners' curiosity, which he believes is also an inspiration from Sai. This digression serves to fulfill a promise made earlier and builds a rapport with the reader before continuing with the sequence of Sai’s life story.
