What reason does Chapter 23 give for the incarnation of saints on Earth, and what is required for a person to benefit from them?

Chapter 23 explains that saints incarnate on this earth out of benevolence, specifically for the salvation of 'dull-witted souls,' which is described as a grace of the Almighty. The text suggests that one's ability to benefit from these saints is not a given. According to this chapter, only if a person has sufficient merit (Punya) in store will a desire even arise in their heart to hear the stories of saints. It is this desire to listen to their stories and teachings that ultimately leads to attaining happiness and contentment, as mentioned in Chapter 23.
