Can you elaborate on the profound philosophical meaning behind Sai Baba giving Udi to his devotees, based on Chapter 33?

Chapter 33 of the Sai Satcharitra reveals that the distribution of Udi was not just a simple blessing but a profound philosophical teaching. The chapter poses the question of the Udi's significance and provides a clear answer from Baba's perspective. The sacred ash is meant to serve as a constant reminder that the entire visible universe is transient and, in essence, 'nothing but ash.' It teaches that the human body, described as being made of five elements, is like wood that is consumed after its destined experiences are exhausted, ultimately becoming ash. As the chapter states, Baba gave the Vibhuti so that we may remember this truth, recognizing that while the universe is pervaded by Maya (illusion), Brahman alone is the ultimate reality.
