How does Chapter 8 connect the idea of the body's impermanence with the ultimate goal of human existence?

Chapter 8 masterfully links the transient nature of the physical body to the higher purpose of human life. It first establishes the body's impermanence by comparing it to a lamp flame that is different every moment and describing it as a foul vessel where "death is placed at every moment." According to the philosophy presented in Chapter 8, this stark reality of the body's decay and impurity serves as a powerful motivator. It implies that since the physical form is so temporary and flawed, focusing solely on bodily pleasures is a waste. This realization is meant to guide a person toward the true goal of human birth: the "realization of the Eternal" and the attainment of the Supreme Self, which is the only true success for a human.
