According to Chapter 33, what is the deeper philosophical meaning behind Sai Baba distributing Udi to his followers?

Chapter 33 reveals the profound spiritual significance of Sai Baba giving Udi. The sacred ash serves as a powerful lesson in impermanence, teaching that the entire visible universe is ultimately as transient as ash. The chapter explains Baba's intention was to remind us that the human body, made of five elements, is like a piece of wood that exists only to experience its destiny. Once those experiences are exhausted, it becomes motionless and turns to ash. By giving this Vibhuti, Baba encouraged devotees to maintain a constant awareness that the universe is pervaded by Maya (illusion) and that only Brahman is the ultimate, unchanging reality.
