According to Sai Baba's teachings, what are the spiritual dangers of being argumentative and engaging in dualistic explanations?

According to the teachings found in Chapter 2, a mind inclined toward argumentation is filled with ignorance and Maya. The text explicitly warns against this, stating that where there is a mind for argumentation, there is no purity of self-interest, only bad thoughts and false logic. Sai Baba advises against establishing one's own side or refuting another's, calling such dualistic explanations a 'useless effort.' This disposition makes a person unfit for self-knowledge, as ignorance devours them, leading to unhappiness in both this world and the next. The author himself admits to having been prone to argumentation before understanding the Satguru's greatness.
