According to Chapter 33, what is the deeper philosophical meaning behind Sai Baba giving Udi to his devotees?

Chapter 33 of the Shri Sai Satcharitra delves into the profound spiritual significance behind Sai Baba's practice of distributing Udi. The act was not merely a ritual but a powerful teaching. The Udi symbolizes the transient and ephemeral nature of the entire visible universe, reminding us that everything eventually turns to ash. Baba used it to teach that the human body, composed of five elements, is temporary and will also become ash once its destined karmic experiences are exhausted. As mentioned in the chapter, by giving the Udi, Baba was imparting a constant reminder of this impermanence and encouraging detachment. It served as a sign that Brahman, the ultimate reality, is the only truth, while the universe we perceive is pervaded by Maya, or illusion.
