What does Chapter 23 teach about the purpose of saints and how one should perceive them?

In Chapter 23, it is stated that saints incarnate on earth out of benevolence, specifically for the salvation of "dull-witted souls," which is described as a grace of the Almighty. The chapter strongly advises against judging a saint by external factors, noting that one cannot understand their true state by observing their caste or what they eat, as their reality is always beyond such things. Furthermore, it suggests that if a person develops a desire in their heart to hear the stories of saints, it is a sign that they have accumulated merit (Punya) and are on a path to happiness and contentment.
