Why does this text discourage argumentation and logic, and what does it say is the consequence of such a mindset?

The text presented in Chapter 2 posits that a mind inclined towards argumentation is filled with ignorance and Maya, not a path to enlightenment. It warns that where there is argumentation, there is no 'purity of self-interest,' only 'bad thoughts and false logic.' According to the chapter, a person with this mindset is not fit for self-knowledge and is destined for unhappiness in both this life and the next. Sai Baba is quoted as directly advising against engaging in dualistic explanations, refuting others, or even establishing one's own side, deeming it a 'useless effort.'
