Chapter 8 uses the analogy of a lamp's flame to describe the human body. What is the meaning behind this comparison?

In Chapter 8, the analogy of a lamp's flame is used to illustrate the transient and ever-changing nature of the human body. The text explains that just as the flame of a lamp appears to be the same from beginning to end but is actually different every single moment, the body is in a constant state of flux. It may seem singular and consistent, but what is seen one moment perishes in the next. This metaphor, as presented in Chapter 8, emphasizes the impermanence of our physical form and how the stages of life, like childhood, youth, and old age, transition into one another without us ever noticing the precise moment of change.
