What is the philosophical lesson Sai Baba intended to teach by giving Vibhuti, as explained in this chapter?

Chapter 33 of the Shri Sai Satcharitra explains the profound philosophical lesson Sai Baba imparted by distributing Vibhuti, or Udi. The giving of the sacred ash was a method to teach that the entire visible universe is as transient and insubstantial as ash. Baba's intention, as described in this chapter, was to instill the awareness that our physical bodies are temporary and will ultimately return to dust once our destined experiences are exhausted. The Vibhuti serves as a constant reminder of this truth, encouraging detachment and the understanding that Brahman alone is the ultimate reality, while the cosmos is pervaded by Maya, or illusion.
