What is the philosophical perspective on human life presented in Chapter 8 of the Sai Satcharitra, especially when compared to animals?

Chapter 8 of the Sai Satcharitra presents a profound philosophical argument about the purpose of human existence. It posits that the true duty of a human is the attainment of the Supreme Self (Paramatman). The text critically questions a life spent merely on basic survival activities like eating, sleeping, procreating, and avoiding fear. It draws a direct comparison to animals like dogs and pigs, stating that if a human's life is only about nourishing the body and pursuing sensual pleasures, then this human birth is useless and no different from that of an animal. As Chapter 8 pointedly asks, if both humans and dogs are in the same state of focusing on survival, wherein lies the greatness of the human body?
