How does Chapter 47 describe the law of Karma and its implications for human birth?

According to Chapter 47, the law of Karma is described as being "very deep; no one can comprehend it." It is a force that even the highly learned can be deceived by, while the ignorant but faithful may be saved. The chapter explains that one's actions have direct consequences, stating that by committing great sins, one "attains a birth corresponding exactly to one's actions." The text further elaborates with the phrase "As the action, so the hearing," suggesting that our experiences are a result of our past deeds. Chapter 47 warns that beings receive a body exactly like what they have earned, emphasizing the importance of using the "priceless opportunity of human birth" wisely to attain self-knowledge before the body falls.
