What does Chapter 19 say is the ultimate goal of human birth and what is required to achieve it?

According to the wisdom in Chapter 19, the ultimate fulfillment and duty of human birth is to attain eternity, fearlessness, liberation, independence, and the realization of the Supreme Self. The chapter clearly states that this liberation cannot be achieved without knowledge. Furthermore, this essential knowledge cannot be attained without detachment. The text explains that the spark of detachment only arises when the mind begins to perceive the world and its attachments as transient and impermanent. Therefore, the path to liberation begins with understanding the fleeting nature of worldly existence.
