Could you explain the deeper spiritual significance of the Udi that Sai Baba distributed, based on the teachings in Chapter 33?

Chapter 33 of the Sai Satcharitra delves into the profound philosophical meaning behind Sai Baba's distribution of Udi. The chapter explains that the Udi serves as a powerful symbol for the impermanence of the material world. Baba's intention in giving the sacred ash was to remind devotees that the entire visible universe is transient, ultimately like ash. The text states that the human body, made of five elements, is also temporary and will become ash once its destined experiences are over. As Chapter 33 clarifies, the Udi is a sign that 'Brahman alone is real, the cosmos is infinite,' urging devotees to maintain this awareness and rise above worldly attachments.
