Based on Chapter 33, what is the deep philosophical meaning Sai Baba intended to convey by distributing Udi?

Chapter 33 delves into the profound spiritual significance of the Udi distributed by Sai Baba. The chapter poses the question of Baba's intention and explains that the Udi is a powerful symbol for the transient nature of the physical world. Baba used it to teach that the entire visible universe is ultimately ephemeral, like ash. As stated in this chapter, the Udi serves as a reminder that the human body, described as "wood made of five elements," will also turn to ash once its destined experiences are complete. The text clarifies that the entire universe is pervaded by Maya (illusion), and Brahman alone is the ultimate reality, a truth symbolized by the Udi.
