Chapter 33 mentions the philosophical significance of Udi. What deeper meaning did Sai Baba intend to convey by distributing it?

Chapter 33 explains that Sai Baba's act of giving Udi was imbued with profound spiritual lessons. The sacred ash, or Vibhuti, was meant to teach devotees about the impermanence of the physical world. The Udi symbolizes that the entire visible universe is transient and will ultimately turn to ash. Furthermore, it serves as a powerful reminder that the human body, made of five elements, will also become ash once its destined experiences are exhausted. Baba gave the Udi so that both he and his devotees would maintain this awareness, understanding that Brahman alone is the ultimate reality while the cosmos is an illusion, or Maya.
