How does Chapter 33 describe the philosophical lesson Sai Baba imparted through the act of giving Udi?

Chapter 33 delves into the profound spiritual meaning behind Sai Baba's distribution of Udi. The chapter explains that Baba used Udi as a powerful symbol to teach about the nature of existence. By giving the sacred ash, He was conveying the message that the entire visible universe is as transient as ash. The text explicitly states that the body, made of five elements, is like wood that will eventually become ash once its destined experiences are exhausted. As mentioned in this chapter, the Udi is a sign that while the universe is pervaded by Maya (illusion), Brahman alone is the ultimate, unchanging reality. Therefore, accepting Udi was accepting this fundamental spiritual truth about detachment and permanence.
