What path towards liberation and self-realization is outlined in Chapter 19?

Chapter 19 clearly states that the ultimate duty of human birth is to attain the Supreme Self, which brings eternity, fearlessness, and liberation. The path to this goal is meticulously laid out. The text emphasizes that there can be no liberation without knowledge. Furthermore, this essential knowledge cannot be attained without detachment. The chapter explains that this sense of detachment only sparks when the mind truly perceives the transient and impermanent nature of the world. As long as one holds onto the ego of being the 'doer' and 'enjoyer,' the experience of pleasure and pain is unavoidable, hindering liberation.
