I've heard that faith is more important than knowledge in Sai's path. Does Chapter 12 talk about this?

Yes, Chapter 12 strongly emphasizes the power of faith over intellectual pride. The text criticizes those who are "intoxicated with the pride of knowledge" and use it to obstruct the path of devotion, warning that their end "does not seem good." It contrasts this with an ignorant person who, through the power of simple faith, can cross the crisis of worldly existence. The chapter clearly states that the "stiffness of dry knowledge is fruitless" and that firm faith is what truly manifests. By placing faith at the feet of a saint, even an ignorant person's ignorance can be destroyed, a feat that eludes proud scriptural scholars, as mentioned in Chapter 12.
