According to Chapter 8 of Sai Satcharitra, what is the true purpose of being human, and how does it differ from just living?

Chapter 8 of the Shri Sai Satcharitra posits that the true purpose of human life extends far beyond mere survival. The text questions if life is simply about being born, growing strong, and living a long time, suggesting that if life is wasted only on activities like eating, sleeping, fear, and mating, there is no difference between a human and an animal like a dog or pig. As explained in this chapter, the true duty and success of human birth is the attainment of the Supreme Self (Paramatman) and the realization of the Eternal. It is this unique potential for spiritual realization that distinguishes human existence and makes it meaningful, rather than a useless endeavor focused only on nourishing the body.
