What are the key philosophical questions about existence that Chapter 8 of the Sai Satcharitra raises, and who is considered 'proficient' in life?

Chapter 8 delves into deep philosophical territory by posing several fundamental questions about our existence. Specifically, it asks: "Where have we come from? Who are we? What is the reason for human birth?" According to the text, a person who knows this "seed," or the answers to these profound questions, is considered proficient. The chapter emphasizes that without this self-knowledge, all of life's efforts are just exhaustion. This proficiency is directly linked to the ultimate goal of human life, which is described as the realization of the Eternal, marking the true success of one's birth.
