How does Chapter 8 use analogies to describe the fleeting and impure nature of the human body?

In its philosophical discourse, Chapter 8 employs powerful analogies to illustrate the nature of the physical body. It compares the body to the flame of a lamp, which appears constant and singular from beginning to end but is, in reality, different every single moment. This highlights the body's transient state, where what is seen one moment perishes in the next. The chapter further provides a stark description of the body's physical reality, calling it a 'washroom of excrement and urine, a foul place of phlegm, pus, and saliva.' This graphic depiction serves to underscore the body's impurity and impermanence, reminding the reader that death is placed at every moment.
