What is Sai Baba's perspective on argumentation and dualistic thinking, and why is it discouraged?

Sai Baba holds a very critical view of argumentation and dualistic explanations, strongly advising against them. As detailed in Chapter 2, He teaches that a mind inclined towards argumentation is filled with ignorance and Maya. He states that in such a mindset, there is no purity, only "bad thoughts and false logic." A person with this disposition is considered unfit for self-knowledge and is destined for unhappiness in this life and the next. Therefore, Baba advises devotees not to establish their own side or refute another's, calling such "useless effort" a barrier to spiritual progress and true happiness.
