How does the Shri Sai Satcharita connect the concepts of Maya, Brahman, and the human body to the sacred Udi?

Chapter 33 of the Shri Sai Satcharita draws a direct line between the Udi and profound Vedantic concepts. It teaches that the Udi is a physical symbol for the truth that 'Brahman alone is real' while the rest of the cosmos is pervaded by Maya, or illusion. The text explicitly states that the sacred ash, or Vibhuti, is given to remind us that the entire visible universe is ultimately nothing but ash. This includes our own bodies, described as 'wood made of five elements,' which will eventually become ash once their destined course is run. The Udi is thus a sign of this truth, urging constant awareness of life's impermanence.
