How does Chapter 8 use the analogy of a lamp's flame to explain the nature of the human body?

In Chapter 8, the transient and ever-changing nature of the human body is illustrated with the metaphor of a lamp's flame. The text explains that although a flame appears constant and singular from beginning to end, it is actually different in every single moment. This is used to describe the state of the body. The chapter elaborates that what we see one moment perishes in the next, and the body that exists right now is not the same body that will exist in the following moment. This analogy powerfully conveys the impermanence of our physical form, a key philosophical point in the chapter.
