Can you explain Chapter 8's perspective on how human life is typically wasted and what constitutes a truly successful birth?

Chapter 8 of the Sai Satcharitra explains that life is often wasted on mundane activities. It states that half of life is spent in sleep, while childhood is lost to play, youth to passion, and old age is consumed by infirmity and disease. This chapter contrasts this squandered existence with the potential for a truly successful birth. According to the text, the 'true success of birth' is the 'realization of the Eternal,' which makes a human being 'free, fearless, and independent.' This involves a deep inquiry into fundamental questions such as 'Where have we come from? Who are we?' Without this self-knowledge, the chapter suggests, all of life's efforts are just 'exhaustion.'
