Why did Sai Baba and the author warn against argumentation and dualistic explanations?

The text in Chapter 2 strongly advises against argumentation. Sai Baba is quoted as saying that a mind focused on argumentation is filled with ignorance and Maya, leading to bad thoughts and false logic. He warns that such a person is unfit for self-knowledge and will find only unhappiness. The core message is to avoid establishing one's own side or refuting another's, labeling such dualistic explanations as "useless effort." The author recalls these words to emphasize that the path to spiritual realization lies in faith and devotion, not in intellectual debate which only reinforces the ego and obstructs true understanding.
