What does Chapter 8 identify as the ultimate achievement for a human being, and who is considered 'proficient' in life?

According to Chapter 8 of the Sai Satcharitra, the ultimate achievement or "true success" of human birth is the "realization of the Eternal." The text posits that a human being is uniquely free, fearless, and independent, and this freedom should be used to pursue this spiritual goal. The chapter defines a "proficient" person as one who understands the fundamental questions of existence: "Where have we come from? Who are we? What is the reason for human birth?" One who knows this "seed," or core truth, is considered accomplished. In contrast, the chapter suggests that without this knowledge, all other life activities are merely "exhaustion."
