How does Chapter 8 describe the transient and ever-changing nature of the human body?

Chapter 8 uses powerful analogies to describe the impermanence of the physical body. It compares the body to the flame of a lamp, which appears to be the same from beginning to end but is in fact different every single moment. The text explains that what is seen one moment perishes in the next, and though the body seems singular, it is infinite in its constant change. Furthermore, Chapter 8 describes the body in stark terms as a 'washroom of excrement and urine' and a foul place, emphasizing that death is placed at every moment, highlighting its fragile and temporary nature.
