What does the Udi from Sai Baba's Dhuni represent about our bodies and the universe?

The Udi, or sacred ash, from Sai Baba's Dhuni carries a deep symbolic meaning about our bodies and the universe, as explained in Chapter 33. The text clearly states that the Udi is meant to show that 'all this visible universe is nothing but ash.' It teaches that the human body is like 'wood made of five elements,' which exists to experience its destiny. Once those experiences are complete, the body becomes motionless and will turn into ash. Therefore, as Chapter 33 conveys, Baba distributed the Udi as a constant reminder of life's impermanence and the transient nature of our physical forms.
