According to Sai Baba in Chapter 2, under what circumstances was it acceptable to engage in dualistic explanations and refute the other side's argument?

According to the excerpts from Chapter 2, there are no circumstances where engaging in such arguments is acceptable. Sai Baba's instruction on this matter is absolute and unambiguous. He explicitly states, "Do not establish your own side, do not refute the other side, Do not engage in dualistic explanations. Why such useless effort?" The chapter goes on to explain that a mind inclined toward argumentation is filled with "abundance of ignorance and Maya" and is unfit for self-knowledge. Instead of providing exceptions, the text strongly warns against this behavior, stating it only leads to unhappiness in this world and the next.
