How does Chapter 47 explain the law of Karma and its relationship to one's birth?

According to Chapter 47, the law of Karma is described as "very deep," a principle so profound that even the highly learned can be deceived by it, while the faithful but ignorant are saved. The chapter explicitly states that one's future birth corresponds exactly to one's actions, quoting "As the action, so the hearing." It explains that beings receive a body precisely as they have earned through their past deeds and consciousness. The text warns that before the body falls, one must not waste the "priceless opportunity of human birth" but should strive for self-knowledge, thereby framing Karma as a direct and inescapable consequence of one's conduct.
