How does Chapter 47 elaborate on the concepts of Karma and rebirth?

Chapter 47 provides a concise yet profound explanation of Karma and rebirth. It describes the law of Karma as being 'very deep' and difficult to comprehend, noting that even the learned can be deceived by it. The chapter asserts that one's future births are directly linked to their actions in their current life, stating, "As the action, so the hearing." It further clarifies that births occur according to one's consciousness or wisdom, and beings receive a body that is an exact match for what they have earned through their deeds. Therefore, as Chapter 47 concludes, the truly wise person is one who uses the 'priceless opportunity of human birth' to attain self-knowledge before death.
