According to the text, what does Chapter 8 of the Sai Satcharitra say about the nature of the physical body and the passage of time?

Chapter 8 of the Sai Satcharitra describes the physical body as transient and impermanent. It uses the analogy of a lamp's flame, which appears constant but is different every moment, to illustrate the ever-changing state of the body. The text notes that the transitions from childhood to youth to old age happen without anyone noticing the exact moment of change. Furthermore, Chapter 8 offers a graphic description of the body as a "washroom of excrement and urine, a foul place of phlegm, pus, and saliva," emphasizing its impurity and the fact that death is a constant, ever-present possibility.
