What is the deeper philosophical meaning behind Sai Baba distributing Udi, as explained in Chapter 33?

Chapter 33 of the Sai Satcharitra explains the profound spiritual symbolism behind the Udi. The text clarifies that Baba's act of giving Vibhuti (sacred ash) was meant to convey a powerful lesson about the nature of existence. The Udi signifies that the entire visible universe is transient and ultimately as ephemeral as ash. It serves as a reminder that the human body, described as being made of five elements, is temporary and will also turn to ash once its destined experiences are exhausted. As stated in this chapter, the Udi is a sign that while the universe is pervaded by Maya (illusion), only Brahman is the ultimate reality. Baba gave the Udi to help devotees remember this truth and cultivate detachment from worldly attachments.
