The text describes the human body as transient and foul. How does this concept of impermanence support the argument for seeking the Paramatman?

The philosophy in Chapter 8 uses the transient nature of the body to argue for a spiritual goal. It compares the body to the flame of a lamp, which appears constant but is different every moment, stating, "What is seen one moment perishes the next." It further describes the body as a "washroom of excrement and urine, a foul place of phlegm, pus, and saliva," where death is a constant possibility. By establishing the physical form as fleeting, impermanent, and fundamentally impure, the text makes a case that focusing on its desires is a waste. This grim reality of the body's nature is used to pivot the reader's focus toward the only thing that is not transient: the realization of the Eternal or Supreme Self (Paramatman), which is presented as the only true success of human birth.
