Can you explain the key questions a person must ask themselves to determine if they are on the right path, as suggested by the text?

Chapter 8 suggests that true proficiency in life comes from deep self-inquiry. It states that one must ponder fundamental questions to avoid a life of mere exhaustion. The text specifically asks: "Where have we come from? Who are we? What is the reason for human birth?" It posits that a person who knows the "seed" of these answers is truly proficient. This implies that the right path involves moving beyond the distractions of daily life—the play of childhood, passions of youth, and infirmities of old age—to engage in this profound self-reflection. Without grappling with these existential questions, one cannot achieve the true purpose of human existence, which is the attainment of the Supreme Self, as detailed throughout this chapter.
