What kind of mindset did Sai Baba warn against for those seeking self-knowledge?

In Chapter 2, Sai Baba strongly cautioned against having a mind for argumentation, stating it is a sign of abundant ignorance and Maya. He explained that such a mindset lacks purity of self-interest and is instead filled with bad thoughts and false logic. A person prone to argumentation is considered unfit for self-knowledge and is destined for unhappiness in this world and the next. Baba explicitly advised against trying to establish one's own side or refute another's, labeling such dualistic explanations as a useless effort that hinders spiritual progress.
