According to the text, what are the negative traits of a person who engages in argumentation, and why are they unfit for self-knowledge?

According to Chapter 2, a person with a mind for argumentation is characterized by an abundance of ignorance and Maya, bad thoughts, and false logic. The text states that such an individual lacks the 'purity of self-interest.' They are considered unfit for self-knowledge precisely because this argumentative nature prevents spiritual progress; as the source says, 'only ignorance devours them.' Chapter 2 further explains that such a person is denied happiness in both this life and the next, experiencing 'unhappiness everywhere and always.' Therefore, Sai Baba explicitly advises against engaging in dualistic explanations or trying to refute others, deeming it a 'useless effort.'
