What did Sai Baba say about argumentation and dualistic thinking, and why did He advise against it?

Sai Baba issued a strong warning against engaging in argumentation and dualistic explanations. As recorded in Chapter 2, He stated that where there is a mind for argumentation, there is an abundance of ignorance and Maya. He explained that such a mindset lacks purity of self-interest and is filled with bad thoughts and false logic. According to Baba, a person consumed by this is not fit for self-knowledge and is instead devoured by ignorance, leading to unhappiness in this life and the next. Therefore, He advised against trying to establish one's own side or refute another's, calling such dualistic efforts useless and a barrier to spiritual progress.
