What does Chapter 47 reveal about the law of Karma and the process of rebirth?

Chapter 47 provides a deep reflection on the law of Karma, stating that it is "very deep; no one can comprehend it." The chapter explains that actions committed during one's life lead to a corresponding birth after death, a concept summarized as "As the action, so the hearing." According to the teachings in Chapter 47, consciousness at the time of death is also crucial, as "Births happen according to one's wisdom (consciousness)." The text warns that great sins can lead to a specific kind of rebirth, and it ultimately praises the person who uses the "priceless opportunity of human birth" to attain self-knowledge before the body falls as truly wise.
