What does the text say about people with argumentative minds, and why are they considered unfit for self-knowledge?

In Chapter 2, a strong warning is issued against having an argumentative mind. The text states that where there is a mind for argumentation, there is an abundance of ignorance and Maya, filled with bad thoughts and false logic. Such a person is deemed unfit for self-knowledge because ignorance devours them, and they find no happiness in this world or the next, only perpetual unhappiness. Sai Baba advises against establishing one's own side, refuting others, or engaging in dualistic explanations, calling such efforts useless. The author himself admits to initially having a logic-driven mind before understanding the Satguru's greatness.
