How did the author's view on debating evolve, and what specific event prompted this change in perspective?

The author initially engaged in debating, a trait he later came to see as extremely harmful and born from pride. His perspective shifted dramatically after an interaction where he was given the title 'Hemadpant.' He describes this naming event in chapter 2 as a 'speech-arrow aimed at the debate to destroy my pride.' He realized the name was given 'so that the pride of debating should dissolve.' This lesson was so profound that he considered the name an 'ornament' and concluded that debating is a bad trait that should not touch him for even a moment, leading him to embrace lifelong humility.
