Based on Chapter 23, why do saints incarnate on Earth and what is their true nature?

Chapter 23 of the Sai Satcharitra teaches that saints incarnate on Earth out of benevolence, specifically for the salvation of dull-witted souls. This is described as the grace of the Almighty. The chapter emphasizes that the true state of a saint is always beyond external observations like their caste, their behavior, or what they eat. Having the desire to hear the stories of saints is itself a sign of accumulated merit (Punya), which leads to happiness and contentment. Sai Baba exemplified this by seeing Narayana in all living beings and never considering anyone inferior, demonstrating a state beyond ordinary human judgment.
