How does Chapter 8 use the analogy of a lamp flame to describe the human body and the passage of time?

To explain the subtle and constant change inherent in our existence, Chapter 8 employs the powerful analogy of a lamp flame. The text notes that a flame 'looks the same from beginning to end, but is different every moment.' This metaphor is used to illustrate the state of the human body. Just as the flame is constantly consuming fuel and is technically a new flame from moment to moment, the body is also in a state of perpetual flux. As this chapter explains, although we perceive our bodies as a single, continuous entity through childhood, youth, and old age, what is seen one moment perishes in the next. This analogy powerfully conveys the impermanent and ever-changing nature of our physical form.
