What fundamental questions about existence are posed in Chapter 8, and what does it say makes a person 'proficient' in life?

Chapter 8 poses several deep, existential questions to the reader: "Where have we come from? Who are we? What is the reason for human birth?" According to the text, a person who truly knows the "seed" or the answer to these fundamental questions is considered proficient in life. In contrast, anyone who lives without this knowledge is said to be engaged in mere exhaustion. The chapter emphasizes that the true success of human birth is not found in a long or sturdy life, but in the realization of the Eternal, which makes a person free, fearless, and independent.
