How does Chapter 8 differentiate between a spiritually-oriented human life and one focused on mere survival?

Chapter 8 of the Sai Satcharitra draws a sharp contrast between a life dedicated to spiritual pursuits and one focused solely on physical existence. It argues that if a person's life revolves only around eating, sleeping, fear, and mating, it is rendered useless and is no different from that of an animal. The text explicitly asks what separates humans from dogs and pigs if both are in the same state of satisfying basic urges. In contrast, a spiritually-oriented life is presented as the true fulfillment of human potential. This involves asking fundamental questions like "Who are we?" and "What is the reason for human birth?" to achieve the realization of the Eternal, which the chapter deems the true success of being born human.
