What is the philosophical significance of the Udi that Sai Baba distributed, according to the Shri Sai Satcharita?

The Udi, or sacred ash, distributed by Sai Baba holds profound philosophical meaning. Chapter 33 explains that Baba's intention in giving Udi was to convey a deep spiritual truth: that the entire visible universe is as transient and impermanent as ash. The Udi serves as a reminder that the physical body, composed of the five elements, is temporary. It exists to experience its destined enjoyments, but once those are exhausted, it will become motionless and return to ash. By giving this Vibhuti, Baba encouraged devotees to maintain this awareness and remember that while the universe is pervaded by Maya (illusion), Brahman alone is the ultimate reality.
