What does chapter 23 say about the difficulty of understanding a saint's true nature and the prerequisite for wanting to hear their stories?

Chapter 23 teaches that one cannot understand the true state of a saint by observing external factors like their caste, their specific behaviors, or what they eat, as their reality is always beyond such things. The chapter also posits that saints incarnate on earth out of benevolence for the salvation of dull-witted souls, an act described as the grace of the Almighty. Interestingly, it suggests that a person's desire to hear the stories of saints to attain happiness and contentment is not a random occurrence. Such a desire only arises in the heart if one has a store of merit (Punya) from past deeds.
