How does Chapter 47 explain the law of Karma and its connection to birth?

According to Chapter 47, the law of Karma is described as very deep and difficult for anyone to fully comprehend, noting that even the highly learned can be deceived by it while the faithful but ignorant are saved. The text establishes a direct link between one's actions and subsequent births, stating, "As the action, so the hearing." It further explains that upon death, a person attains a birth that corresponds exactly to their accumulated actions. The chapter mentions that "Births happen according to one's wisdom (consciousness)," and that these beings receive a body precisely like what they have earned. Therefore, Chapter 47 advises that one should not waste the priceless opportunity of human birth but use it to attain self-knowledge.
