Why does the author warn against having a mind for argumentation?

The author issues a strong warning against argumentation because it is seen as a significant spiritual obstacle. Chapter 2 describes a mind given to argumentation as one where there is an abundance of ignorance and Maya. Such a person is considered unfit for self-knowledge because their mind is filled with bad thoughts and false logic, lacking any purity of self-interest. The text goes on to state that this disposition leads to unhappiness in both this world and the next. It directly advises against trying to establish one's own side or refute another's, calling such dualistic explanations a useless effort.
