What is the path to liberation as outlined in the teachings of Chapter 19?

Chapter 19 clearly states that the ultimate goal and duty of human birth is to attain liberation and the Supreme Self. The path to this goal is laid out in a specific sequence. The chapter emphasizes that there can be no liberation without knowledge. Furthermore, this essential knowledge cannot be attained without detachment. The spark of detachment is only ignited when the mind truly perceives the world and its attachments as transient and impermanent. As long as the ego—the sense of being the 'doer' and 'enjoyer' tied to the body and mind—persists, the experience of pleasure and pain is unavoidable, blocking the way to freedom. Therefore, the journey described in Chapter 19 begins with seeing the world's transient nature.
