How does Chapter 33 connect Sai Baba's practical actions, like tending the fire, to the spiritual lesson of impermanence?

Chapter 33 masterfully connects Sai Baba's physical actions to a deep spiritual lesson. It first outlines the practice: Baba would buy firewood and offer the logs into the Dhuni, producing Udi. The chapter then explicitly asks about the significance of this ritual. The answer provided is that the entire process was a living sermon on impermanence. The firewood represents the material world and the physical body, which are consumed by the fire of time and karma, ultimately leaving only ash. By distributing this Udi, as explained in this chapter, Baba gave a tangible symbol of this truth, reminding devotees that all forms are temporary and encouraging them to seek the eternal reality of Brahman.
