Why does the author of the 'Sai Leela' book pause the main narrative to explain the origin of the name 'Hemadpant'?

The author pauses the main story to address the origin of the name 'Hemadpant' out of consideration for the reader. As explained in Chapter 2, he acknowledges that a doubt naturally arises for listeners who hear "Composed by the devotee Hemadpant" at the end of every chapter. He promises to satisfy this curiosity by telling the sub-story of how this naming ceremony occurred. He assures the reader that listening to this story will reveal its appropriateness and that the decision to include it is, in itself, an inspiration from Sai Baba, after which the main life story will continue.
