What kind of intellectual approach does Sai Baba advise against for those on a spiritual path?

As detailed in Chapter 2, Sai Baba strongly advises against a mindset rooted in argumentation and dualism. He warns that where there is a mind for argumentation, there is an abundance of ignorance and Maya, filled with bad thoughts and false logic. Such a person is deemed unfit for self-knowledge. Baba explicitly counsels, "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations." He dismisses such intellectual debates as a "useless effort" that prevents one from attaining happiness in this world or the next.
