Why do saints incarnate on earth, and what determines if a person will be drawn to their stories?

As detailed in Chapter 23, the incarnations of saints occur on this earth out of benevolence, specifically for the salvation of "dull-witted souls." This is described as a grace of the Almighty. The text suggests that one's ability to appreciate these divine figures is not accidental. It states that only if a person has a store of merit (Punya) will a desire arise in their heart to hear the stories of saints, which in turn leads them to attain happiness and contentment. This implies a spiritual readiness is necessary to benefit from the saints' teachings.
