Drawing from Chapter 8, why is a human being considered distinct from animals or inanimate objects, and what is the 'true success' of human birth?

Chapter 8 distinguishes humans from animals and objects by highlighting the potential for spiritual realization. The text argues that if life is only about basic functions like breathing, eating, and procreating, then humans are no different from a blacksmith's bellows that breathes or dogs and pigs that fill their bellies. The chapter states that a human being is uniquely 'free, fearless, and independent.' Therefore, the 'true success' of human birth is not mere survival or sensual pleasure but the realization of the Eternal. It poses the fundamental questions 'Where have we come from? Who are we?' and suggests that one who knows this 'seed' is proficient, while all else is just exhaustion.
