Based on Chapter 33, how did Sai Baba's daily actions with the Dhuni and Udi serve as a constant, practical lesson in detachment and the nature of reality?

Chapter 33 of the Shri Sai Satcharita illustrates how Sai Baba's daily rituals were a profound, practical teaching on detachment. The entire process—from buying firewood, to offering it into the ever-burning Dhuni, and finally distributing the resulting ash (Udi)—was a living sermon. This daily action served as a constant, tangible reminder that the body, like the wood, is destined to become ash once its purpose is served. By giving the Udi, Baba was imparting the philosophical lesson that the physical world is illusory (Maya) and transient. He encouraged devotees to maintain this awareness, reminding them that Brahman is the only ultimate reality.
