Why did Sai Baba want the author to engage in argumentation, and what were the main points of the 'dualistic explanations' he was supposed to master?

The provided text from Chapter 2 indicates that Sai Baba advised against argumentation, rather than encouraging it. The author recalls Baba's words: "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations. Why such useless effort?" This guidance was given to counter the author's original nature, which, as Chapter 2 describes, was prone to argumentation. Baba taught that where there is a mind for argumentation, ignorance and Maya abound, and such a person is not fit for self-knowledge or happiness.
