According to Chapter 33, what is the deeper philosophical meaning behind Sai Baba's practice of distributing Udi?

Chapter 33 delves into the profound spiritual significance of Udi, moving beyond the daily ritual. The chapter explains that Baba's distribution of Vibhuti (sacred ash) was meant to convey a powerful lesson about the nature of existence. The Udi symbolizes that the entire visible universe is ultimately as transient as ash. It serves as a reminder that our own bodies, described as being made of five elements, will also become ash once their destined experiences are exhausted. As this chapter teaches, Baba gave the Udi to instill this constant remembrance that the material world is impermanent and that Brahman alone is the ultimate, unchanging reality.
