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

In its philosophical discourse on the nature of existence, Chapter 8 uses the analogy of a lamp's flame to illustrate the transient yet continuous 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, it is actually different in every single moment. Similarly, the human body seems like a singular, continuous entity through childhood, youth, and old age. However, the chapter reveals that what is seen one moment perishes in the next; the body that exists now is not the same in the next moment, highlighting its constant state of flux and impermanence.
