Can you explain the analogies of the lamp flame and the blacksmith's bellows as used in Chapter 8 to illustrate the nature of the body and life?

Chapter 8 of the Sai Satcharitra employs several powerful analogies to convey deep philosophical points. The text compares the human body to the flame of a lamp, explaining that while it may look the same from one moment to the next, it is actually different every instant. This illustrates the transient and ever-changing state of our physical form. Another analogy mentioned is the blacksmith's bellows, which is used to question the value of a life focused only on basic functions. The chapter implies that just as a bellows breathes but is not truly alive in a meaningful sense, a human who only performs basic biological functions without seeking higher truth is not fulfilling their purpose. These analogies from Chapter 8 serve to highlight the fleeting nature of the body and the need for a purpose beyond mere existence.
