I saw the name 'Hemadpant' at the end of the chapter. Who is that, and what was he like before?

The author, who writes the "Sai Leela" book, introduces the story of how he was named "Hemadpant." In Chapter 2, he explains that the pen name "Hemadpant" is heard at the end of every chapter and that a doubt naturally arises about this person's identity. To satisfy this curiosity, he begins to tell the story of this naming. As described in Chapter 2, the author confesses that he was initially a mischievous, talkative, cynical, and critical person. He admits to being arrogant about his knowledge, having a logic-driven mind, and being proud of his own wisdom, which made him prone to argumentation before understanding the greatness of a Satguru.
