What philosophical points does Chapter 8 make about the transient nature of the body and the passage of time?

Chapter 8 explores the impermanence of existence by using a powerful analogy. It compares the body to the flame of a lamp, which appears to be the same from beginning to end but is actually different every moment. This illustrates how the body is in a constant state of flux, though it seems singular. The chapter also notes how the stages of life—childhood, youth, and old age—come and go without anyone noticing the exact transition. It emphasizes that what is seen one moment perishes in the next. This philosophical reflection on the fleeting nature of the body and life serves to underscore the urgency of pursuing spiritual practice before time runs out.
