According to Chapter 8, what is the true purpose of being human, and how is it different from just being an animal?

Chapter 8 of the Sai Satcharitra presents a profound philosophical view on the purpose of human life. It argues that the true duty of human birth is the attainment of the Supreme Self (Paramatman) and the realization of the Eternal. The text explicitly questions whether life is merely for growing strong, breathing, and living a long time. It differentiates human potential from animal existence by stating that if a life is spent only on activities like eating, sleeping, fear, and mating, there is no difference between a human and animals like dogs or pigs. As Chapter 8 posits, such a life, focused only on nourishing the body and sensual pleasure, renders the precious human birth useless.
