According to the philosophy presented in Chapter 8, how is a typical life wasted across its different stages?

Chapter 8 presents a critical examination of how a typical human life is spent without spiritual focus. It states that half of life is lost to sleep and the rest is spent in restlessness. The text then breaks down the stages, explaining how each phase is squandered: childhood is spent in play, youth is consumed by passion for women, and old age is burdened by infirmity and constant disease. This entire progression, as described in Chapter 8, is considered a waste because it misses the true purpose of human existence, which is the realization of the Supreme Self, making it no better than the life of an animal focused only on survival.
