How did the author of the Sai Satcharita come to be known as 'Hemadpant', and what was his initial disposition?

The author himself addresses the origin of his name, 'Hemadpant,' which appears at the end of every chapter, promising to satisfy the reader's curiosity. Chapter 2 describes the author's initial character as mischievous, talkative, cynical, and critical. He was arrogant about his knowledge, possessing a logic-driven mind that was always proud of its own wisdom and prone to argumentation. He knew nothing of a Satguru's greatness. The story of how he received this name is presented as a sub-story within the larger narrative of Sai's life, an inspiration from Sai himself to explain its appropriateness.
