Why did Sai Baba caution against argumentation and a dualistic mindset, and what did he say would be the fate of such a person?

Sai Baba strongly advised against an argumentative and dualistic mindset because he equated it with ignorance and Maya. As detailed in Chapter 2, he warned that where there is a mind for argumentation, there is no purity of self-interest, only "bad thoughts and false logic." He considered such a person unfit for self-knowledge, as they become devoured by ignorance. The fate of such an individual is bleak; Sai states there is no happiness for them in this world or the next, only unhappiness "everywhere and always." He therefore advised against engaging in dualistic explanations or trying to refute others, deeming it a "useless effort" that hinders spiritual progress.
