According to Chapter 8, what are the ways a human life can be wasted, and what is the alternative?

Chapter 8 of the Sai Satcharitra presents a critical view of how a human life can be squandered. It states that half of life is often lost to sleep and the rest to restlessness. The chapter details how childhood is spent in play, youth is consumed by passion, and old age is burdened by infirmity and disease. The text warns that if life is spent only on the four activities of eating, sleeping, fear, and mating, then the human birth is essentially useless. The alternative proposed in Chapter 8 is to pursue the true purpose of human existence: the attainment of the Supreme Self (Paramatman). This involves introspection and seeking answers to fundamental questions about our origin and identity.
