What does Chapter 12 reveal about the primary function of a saint in the world, especially concerning their devotees and worldly struggles?

Chapter 12 powerfully describes a saint's function as a compassionate guide. Saints are called the "Agastya for the ocean of worldly existence" and the "sun for the darkness of ignorance." It is explained that saints spend their millions of merits, drawn by the love of their devotees, and will leap over any obstacle for their sake. Their purpose is to uplift the distressed and set the wicked on the right path, treating all with equality. In essence, as Chapter 12 illustrates, their role is to use their compassion and power to help souls navigate the struggles of life and ignorance.
