Based on the teachings in Chapter 33, what was the lesson about the human body that Sai Baba conveyed through the distribution of Udi?

In Chapter 33 of the Sai Satcharitra, Sai Baba used the Udi to impart a significant lesson about the human body and its transient nature. The text explains that the Udi symbolizes that all of the visible world is ultimately nothing but ash. It then applies this concept directly to the human form, stating that the body is like wood composed of the five elements. It exists to experience its destined enjoyments and karmic consequences. However, once those experiences are exhausted, the body becomes motionless and will inevitably turn into ash. As Chapter 33 recounts, by giving the Vibhuti (Udi), Baba was encouraging both himself and his devotees to constantly remember this impermanence, fostering detachment from the physical form.
