What is the purpose of saints' incarnations on Earth, based on the teachings in Chapter 23?

As detailed in Chapter 23, the incarnations of saints occur on Earth out of benevolence, specifically for the salvation of "dull-witted souls." This act is described as a form of grace from the Almighty. The text further elaborates that a person must have accumulated merit (Punya) to even develop the desire in their heart to hear the stories of these saints. By engaging with these narratives, devotees can attain happiness and contentment, fulfilling the benevolent purpose of the saints' presence among humanity.
