What does Chapter 8 reveal about the transient nature of the physical body and how does that relate to life's purpose?

Chapter 8 emphasizes the impermanence of the physical body to steer focus towards a higher spiritual goal. It compares the body to the flame of a lamp, which seems singular but is different every moment, and notes that what is seen one moment perishes the next. The text further describes the body as a "foul place of phlegm, pus, and saliva" where "death is placed at every moment." This stark depiction of the body's transient and unpleasant nature serves to detach a person from physical identification and reinforces that the true purpose of life is not bodily preservation but the realization of the Eternal Self.
