What mental habits does Sai Baba warn against in Chapter 2, and why are they considered harmful?

According to the teachings in Chapter 2, Sai Baba strongly advises against a mind preoccupied with argumentation, dualistic explanations, and the impulse to establish one's own side while refuting others. He warns that where there is a mind for argumentation, there is an abundance of ignorance and Maya, leading to bad thoughts and false logic. Such a mindset is considered extremely harmful because it makes a person unfit for attaining self-knowledge and is said to bring unhappiness in both this world and the next. Baba considers these intellectual debates to be a "useless effort" that prevents the attainment of true happiness and self-realization.
