What was Sai Baba's warning regarding argumentation and a logical mind?

Sai Baba issued a strong caution against a mind inclined towards argumentation and debate. In Chapter 2, He states that where there is a mind for argumentation, there is an abundance of ignorance and Maya. He clarifies that in such a state, there is no purity of self-interest, only bad thoughts and false logic. Baba warns that such a person is not fit for self-knowledge and is instead devoured by ignorance, leading to unhappiness in this life and the next. He directly advises, "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations. Why such useless effort?"
