Based on Chapter 19, what is the ultimate purpose of human life and what steps are necessary to achieve it?

According to the teachings in Chapter 19, the fulfillment and duty of human birth is to achieve eternity, fearlessness, liberation, independence, and the attainment of the Supreme Self. The path to this goal is clearly outlined: the text states there can be no liberation without knowledge. This knowledge, in turn, cannot be attained without detachment. The spark for detachment arises only when the mind perceives the world as transient. Therefore, the prescribed path involves recognizing the world's impermanence to cultivate detachment, which then leads to the knowledge required for ultimate liberation.
