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

Hemadpant is the name attributed to the author of the "Sai Leela" book. The author himself explains the reason for pausing the main narrative in Chapter 2. He notes that at the end of each chapter, the line "Composed by the devotee Hemadpant" appears, which naturally creates curiosity among listeners about who this person is. To satisfy this curiosity, which he believes is also an inspiration from Sai, he decides to tell the story of how he received this name. He considers it an appropriate sub-story to share after recounting Baba's advice to "not engage in dualistic explanations," promising to resume Sai's life story after this brief but relevant digression.
