Why is argumentation considered a hindrance to spiritual progress in the provided text?

Argumentation is depicted as a significant obstacle to spiritual growth because it stems from ignorance and ego. Chapter 2 explains that where there is a mind for argumentation, there is an "abundance of ignorance and Maya" and a lack of pure self-interest. Such a person, filled with bad thoughts and false logic, is considered unfit for self-knowledge and is destined for unhappiness. Sai Baba's words, quoted in Chapter 2, advise against establishing one's own side or refuting another's, labeling such dualistic explanations as a "useless effort" that prevents one from attaining true happiness and consciousness.
