According to Chapter 8 of Sai Satcharitra, what is the true purpose of human life, and how does it differ from the existence of animals?

Chapter 8 of Sai Satcharitra explores the philosophy of human life, questioning if its purpose is merely to be born, grow, and live a long time. It argues that if life is wasted only on activities like eating, sleeping, fear, and mating, then there is no real difference between a human and animals like dogs and pigs, who also fill their bellies and reproduce. The text explicitly states that the true duty and success of human birth is the attainment of the Supreme Self (Paramatman). As mentioned in this chapter, this realization of the Eternal is what makes a human being unique, free, and fearless, distinguishing our existence from mere survival.
