Can you explain the connection between the human body and the symbolism of Vibhuti as taught by Sai Baba?

Sai Baba used Vibhuti, or Udi, to teach a profound lesson about the human body's impermanence. According to Chapter 33, he explained that the body is like wood, composed of the five elements. Its purpose is to experience its destined enjoyments and karmic consequences. Once these experiences are exhausted, the body becomes motionless and, like the firewood in the Dhuni, will ultimately turn to ash. By giving this Udi, Baba encouraged a constant awareness, both for himself and his devotees, of this transient state, reminding them to look beyond the physical form to the eternal reality.
