Based on Chapter 12, what is the core role of a saint and how should a devotee approach them for spiritual progress?

The core role of a saint, as described in Chapter 12, is to be a compassionate guide who helps souls navigate the "ocean of worldly existence." Saints are depicted as the "sun for the darkness of ignorance," treating all beings with equality. For spiritual progress, the chapter insists that a devotee must approach a saint with firm faith. It warns against intellectual pride, stating that even an ignorant person can be saved by faith, while proud scholars remain stuck. Therefore, according to Chapter 12, the correct approach is to place one's faith at the saint's feet, which will destroy ignorance and allow devotion to arise.
