What specific warnings did Sai Baba issue regarding argumentation and the pursuit of self-knowledge?

Sai Baba gave a stern warning against the pitfalls of an argumentative mind. As detailed in Chapter 2, He stated that where there is a mind for argumentation, ignorance and Maya are abundant, and there is no purity of self-interest, only bad thoughts and false logic. He declared that such a person is not fit for self-knowledge and will be devoured by ignorance, leading to unhappiness in both this world and the next. His direct instruction was, "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations," deeming such efforts as useless.
