What does Chapter 8 of the Sai Satcharitra say about the true purpose of human life, and how does it contrast this with the lives of animals?

Chapter 8 of the Sai Satcharitra delves into the philosophy of human existence, questioning if life's purpose is merely to be born, grow strong, and live a long time. It argues that the true duty of a human is the attainment of the Supreme Self (Paramatman). The text contrasts this higher purpose with a life focused solely on basic activities like eating, sleeping, fear, and mating. As explained in this chapter, if these are the only goals, there is no difference between a human and animals like dogs or pigs, who also fill their bellies and reproduce. The chapter concludes that a human birth focused only on bodily nourishment and pleasure is ultimately useless.
