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

In its philosophical discourse, Chapter 8 uses a powerful analogy to illustrate the body's transient nature. It compares the body to the flame of a lamp, which appears constant and singular but is, in reality, different every single moment. The chapter explains, 'What is seen one moment perishes the next; though it seems singular, it is infinite. The body that exists this moment is not the same in the next.' This metaphor effectively conveys the continuous and imperceptible process of change. As Chapter 8 further elaborates, the stages of childhood, youth, and old age are visible, but the exact transitions go unnoticed, emphasizing the constant flux that defines our physical existence.
