How does Chapter 12 explain the relationship between saints, their devotees, and those who are ignorant of spiritual matters?

In Chapter 12, the relationship between saints and devotees is depicted as one of profound love, where saints will spend their 'millions of merits' and leap over any obstacle for the sake of a devotee. The chapter also addresses those who are ignorant, who 'wallow in the desire for wife, son, and wealth' and do not know the supreme spiritual goal. It states that God and saints feel pity for these innocent and ignorant ones, and a saint might even devote his life to them. The key for such individuals to progress is 'firm faith,' as the text concludes that the 'stiffness of dry knowledge is fruitless.'
