What constitutes a 'wasted' life according to the philosophy presented in Chapter 8?

According to the teachings in Chapter 8, a life is considered wasted if it is spent without pursuing the ultimate goal of realizing the Supreme Self. The text outlines how this happens: half of life is lost to sleep and the rest to restlessness. Childhood is spent in play, youth in passion, and old age is burdened by infirmity. If this cycle is all a person experiences, their life is deemed fruitless. The chapter is explicit that if nourishing the body and engaging in sexual pleasure are the "only means and ends of this life, then this human birth is useless." A life wasted is one that mirrors that of an animal, focused solely on eating, sleeping, fear, and mating, thereby ignoring the unique human capacity for self-realization.
