What is the philosophical meaning behind Sai Baba giving Udi to his devotees as described in Chapter 33?

Chapter 33 of the Shri Sai Satcharita explains the deep philosophical significance behind Sai Baba's practice of distributing Udi (sacred ash). Baba used this act to convey profound spiritual truths. The Udi served as a powerful symbol to remind devotees that the entire visible universe is transient and ultimately as ephemeral as ash. Furthermore, as described in this chapter, Baba taught that the human body, composed of the five elements, is temporary; once its destined karmic experiences are exhausted, it too will become ash. By giving the Udi, Baba was imparting the lesson that only Brahman is the ultimate reality, while the universe is pervaded by Maya (illusion). This practice was a constant reminder of non-attachment and the true nature of existence.
