How does Chapter 8 describe the physical body and the passage of time?

Chapter 8 presents a profound and rather stark view of the physical body and the nature of time. It uses the analogy of a lamp flame, which appears constant but is different every moment, to illustrate the ever-changing state of the body. The text notes that what is seen one moment perishes in the next and that the transitions between childhood, youth, and old age occur without anyone noticing the exact moment of change. More graphically, Chapter 8 describes the body as a "washroom of excrement and urine, a foul place of phlegm, pus, and saliva." It culminates in the sobering declaration that "death is placed at every moment," emphasizing the body's extreme impermanence and fragility.
