Based on Chapter 12, what is the fundamental role of a saint in relation to their devotees and those who are ignorant?

Chapter 12 describes the role of a saint as one of immense compassion and guidance. It states that saints spend their accumulated merits, drawn by the love of their devotees, and will "leap forward for the sake of the devotee." For those who are ignorant and lost in worldly desires for family and wealth, a saint might even "devote his life to them." The goal is to help firm faith manifest within them, as faith is presented as the key to salvation. Ultimately, the chapter teaches that by placing faith at the feet of saints, the "ignorance of the ignorant is destroyed," making the saint a transformative guide who is like the "sun for the darkness of ignorance."
