What kind of mindset and behaviors does Sai Baba warn against for those seeking self-knowledge?

In the teachings found in Chapter 2, Sai Baba explicitly warns against certain mindsets that hinder spiritual progress. He cautions that a mind inclined towards argumentation is filled with ignorance and Maya, making it unfit for self-knowledge. Such a person, dominated by bad thoughts and false logic, will only be devoured by ignorance and find unhappiness in this life and the next. Sai Baba advises against trying to establish one's own side or refute another's, calling such dualistic explanations a useless effort. The author later reflects on these words, describing his own former self as mischievous, cynical, and critical, with a logic-driven mind and pride in his own wisdom, all of which are traits to be overcome.
