Why do saints like Sai Baba appear on Earth, and what makes a person want to hear their stories, according to Chapter 23?

Chapter 23 of the Sai Satcharitra explains that the incarnations of saints on this earth are an act of benevolence and a grace of the Almighty, specifically for the salvation of "dull-witted souls." Their presence is meant to guide humanity towards liberation. The chapter further clarifies that the desire to hear the stories of these saints is not a random occurrence. It states that only if a person has a store of merit (Punya) from past deeds will a genuine desire arise in their heart to listen to these sacred narratives. Hearing these stories, in turn, is the path to attaining true happiness and contentment.
