Could you elaborate on the message of impermanence that Sai Baba taught through the Udi, as explained in Chapter 33?

Chapter 33 of the Sai Satcharitra provides a deep insight into Sai Baba's teachings on impermanence, using Udi as the medium. The core message was that all of creation, including our own physical forms, is transient. The chapter explicitly states that the Udi shows that 'all this visible universe is nothing but ash.' It further describes the body as being like 'wood made of five elements,' which exists only to experience its destined enjoyments, and once those are exhausted, it too will become ash. By giving this Vibhuti, Baba was providing a constant, physical reminder of this truth. He encouraged followers to maintain this awareness day and night, fostering a sense of detachment from the material world and a focus on the eternal.
