Who is 'Hemadpant' and why does the author pause the main narrative to explain the origin of this name?

Hemadpant is the name attributed to the author of the 'Sai Leela' book, as noted by the credit "Composed by the devotee Hemadpant" at the end of each chapter. In Chapter 2, the author acknowledges that this credit naturally raises curiosity among listeners about who this person is. He decides to tell the sub-story of how he received this name to satisfy that curiosity, assuring readers that this digression is also inspired by Sai Baba. He promises that after this short story about his naming ceremony, the main life story of Sai will continue.
