Why does Chapter 12 issue a strong warning against associating with certain types of scholars, and what are their defining negative traits?

Chapter 12 warns against scholars who, despite being "well-versed in the Vedas and Vedangas," are "intoxicated with the pride of knowledge." Their defining negative traits are having a "dull intellect" that swells "uselessly with dry pride" and a tendency to disparage and obstruct the path of devotion. The chapter considers them a negative influence because their pride separates them from God and prevents spiritual progress; it states their "end does not seem good." This warning, found in Chapter 12, emphasizes that their intellectualism is fruitless and contrasts it with the power of simple faith, which can destroy ignorance and overcome worldly fears.
