What message was Sai Baba conveying about the human body and the material world by continuously distributing sacred ash from the Dhuni?

Through the practice of distributing Udi, as explained in Chapter 33, Sai Baba was conveying a profound message about the nature of existence. The chapter makes it clear that the Udi symbolizes the transient nature of all creation. By giving the ash, Baba taught that the 'visible universe is nothing but ash.' This lesson extended to the human body, which the text describes as 'wood made of five elements' that exists only to experience its destiny and, once that is exhausted, will also become 'just this ash.' Therefore, the continuous distribution of Udi from the Dhuni was a practical, daily sermon on detachment, impermanence, and the importance of remembering the ultimate reality over the illusory attachments of the material world.
