According to Chapter 23, what is the main reason saints incarnate on Earth?

Chapter 23 of the Sai Satcharitra states that the incarnations of saints on this earth happen out of benevolence, specifically for the 'salvation of dull-witted souls.' This is presented not as a random occurrence, but as an act of grace from the Almighty. The chapter further elaborates that having a store of merit (Punya) is what creates the desire within a person's heart to listen to the stories of saints. By engaging with these stories, one can attain happiness and contentment. Therefore, the purpose of a saint's incarnation, like that of Sai Baba, is to provide a pathway to spiritual upliftment and salvation for humanity.
