What warning does the text provide about having an argumentative mind, and how does it affect one's spiritual well-being?

The text issues a strong warning against having a mind inclined towards argumentation. As stated in Chapter 2, where there is a tendency for argumentation, there is an abundance of ignorance and Maya, not a purity of self-interest. Such a person is deemed unfit for self-knowledge and is consumed by ignorance, leading to unhappiness in both this world and the next. Sai Baba questions the "useless effort" of engaging in dualistic explanations, refuting others, or establishing one's own side, suggesting that such intellectual pride is a significant barrier to spiritual progress and true happiness.
