Based on Chapter 19, what is the ultimate goal of human life and what is required to achieve it?

Chapter 19 posits that the ultimate fulfillment and duty of human birth is the attainment of the Supreme Self, which leads to eternity, fearlessness, liberation, and independence. The path to this liberation is clearly laid out. The text states unequivocally that 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 begins to perceive the world and its attachments as transient and impermanent. Therefore, as Chapter 19 explains, recognizing the temporary nature of worldly existence is the crucial first step toward gaining the spiritual knowledge necessary for liberation.
