Can you explain the metaphors used in Chapter 8 to illustrate the transient nature of the human body and the passage of time?

Chapter 8 employs powerful metaphors to convey the fleeting nature of life and the body. To describe the constant, unnoticeable change, it compares life to the flame of a lamp, which looks the same from beginning to end but is actually different every single moment. The chapter also notes how childhood, youth, and old age transition without anyone ever noticing the exact moment of change. The body itself is described as being as transient as a peepal leaf, emphasizing its momentary existence. As Chapter 8 states, 'What is seen one moment perishes the next,' underscoring the urgent need for spiritual realization in the face of such impermanence.
