What is the purpose of saints being born on earth, and how should one approach understanding them, according to Chapter 23?

Chapter 23 teaches that the incarnations of saints occur on earth out of benevolence, as a grace of the Almighty, specifically for the salvation of dull-witted souls. It also provides guidance on how to perceive them, cautioning that one cannot understand a saint's true state by external factors like their caste, their behavior, or what they eat, as their reality is always beyond such things. The desire to hear the stories of saints, which leads to happiness, is said to arise only when a person has sufficient merit (Punya) in store.
