How does Chapter 8 describe the transient and unpleasant nature of the physical body?

Chapter 8 of the Sai Satcharitra uses powerful imagery to illustrate the fleeting and impure nature of the human body. It compares the body to the flame of a lamp, which appears to be constant from beginning to end but is actually different every single moment. The text notes that what is seen one moment perishes in the next. It highlights how major life stages like childhood, youth, and old age pass by without us ever noticing the exact moment of transition. Furthermore, Chapter 8 describes the body in stark terms as a 'washroom of excrement and urine' and a 'foul place of phlegm, pus, and saliva,' emphasizing that death is a constant possibility at every moment, which is considered a great misfortune.
