Based on Chapter 33, what was Baba's message about impermanence that he conveyed by giving Vibhuti (Udi)?

Chapter 33 of the Shri Sai Satcharitra explains that Sai Baba used the distribution of Vibhuti, or Udi, to impart a crucial lesson on impermanence. The chapter poses the question of the Udi's significance and then provides Baba's intended message. The Udi is a powerful symbol showing that the entire visible universe is ultimately as transient as ash. Baba's teaching, as conveyed in this chapter, was that our bodies are temporary vessels that will eventually turn to ash once their karmic journey is complete. By giving the Udi, he was reminding devotees to constantly remember this truth ('Such is the state of yours and mine; may you maintain this remembrance'), helping them detach from worldly attachments.
