What was Sai Baba's specific warning against argumentation and dualistic explanations?

In Chapter 2, Sai Baba delivered a stern warning about the dangers of a contentious mindset. He taught that a mind inclined towards argumentation is filled with ignorance and Maya, and such a person is unfit for self-knowledge and is instead devoured by ignorance. He cautioned that this path leads only to unhappiness in this world and the next. Baba's direct instruction was, "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations. Why such useless effort?" These words deeply influenced the author, who recalled them while explaining his own past tendencies.
