Who is Hemadpant, and why does the author pause the main story to explain this name?

Hemadpant is the name attributed to the author of the "Sai Leela" book, as the phrase "Composed by the devotee Hemadpant" is noted at the end of every chapter. In Chapter 2, the author acknowledges that this naturally creates curiosity for the reader. To satisfy this curiosity, the author promises to tell the sub-story of how he was given this name. This digression is presented as an inspiration from Sai, and it serves to explain the origin of the name before the main life story of Sai continues, making the narrative more complete for the reader.
