Why do saints incarnate on earth, and what prerequisite does a person need to be drawn to their stories, according to Chapter 23?

Chapter 23 explains that the incarnations of saints occur on earth out of benevolence, specifically for the salvation of "dull-witted souls," and this is considered a grace of the Almighty. However, the ability to appreciate them is not universal. The text specifies that a desire to hear the stories of saints, which brings happiness and contentment, will only arise in a person's heart if they have a store of merit (Punya). This implies that having spiritual merit from past actions is a necessary condition to even become interested in the life and teachings of a saint.
