What is the philosophical significance of Sai Baba distributing Udi, as explained in Chapter 33 of the Sai Satcharitra?

Chapter 33 of the Shri Sai Satcharitra delves into the profound philosophical meaning behind Sai Baba's practice of distributing Udi (sacred ash). The chapter explains that this act was a powerful teaching on the nature of reality. Baba used the Vibhuti to demonstrate that the entire visible universe is transient and ultimately as ephemeral as ash. The text clarifies that the Udi is a reminder that the human body, composed of the five elements, is temporary and will become ash once its destined experiences are over. This practice was intended to instill a sense of detachment from the illusory world (Maya) and to help devotees remember that only Brahman, the Absolute, is the true and eternal reality.
