What is the deeper philosophical meaning behind the Udi that Sai Baba distributed, according to the teachings in Chapter 33?

Chapter 33 explains the profound spiritual significance of the Udi given by Sai Baba. The sacred ash served as a powerful teaching tool to illustrate that the entire visible universe is transient and ultimately as insubstantial as ash. Baba's intention was to convey that the human body, described as being made of five elements, is temporary and will also become ash once its destined experiences are exhausted. As Chapter 33 clarifies, the Udi is a sign that Brahman alone is real while the cosmos is an illusion (Maya), and it was given to help devotees maintain this constant awareness.
