How does Chapter 33 connect the physical act of burning wood in the Dhuni to the metaphysical concept of the human body and existence?

Chapter 33 draws a direct and powerful analogy between the physical process in the Dhuni and the nature of human existence. It describes how Sai Baba would offer dry logs of wood into the sacred fire, which would burn down to ash, or Udi. The chapter then explains that this is a metaphor for our own bodies, which it calls "wood made of five elements." Just as the wood burns away, our bodies are destined to become ash once their allotted "enjoyments" or karmic experiences are exhausted. By giving this Udi, Baba was imparting a constant, tangible reminder of life's impermanence and the ultimate state of all material forms.
