What is the connection between Sai Baba's Dhuni fire, the Udi he distributed, and the concept of giving?

The connection is deeply philosophical, linking physical actions to spiritual truths. Chapter 33 describes how Sai Baba would buy firewood and offer it into his sacred Dhuni. The resulting ash, or Udi, which he gave to devotees, was a potent symbol. Baba explained that this Udi signifies that the entire visible universe is as transient as ash. By giving this Udi, he was giving a profound lesson in detachment and the impermanence of the physical body. This act of giving Udi was a reminder to cultivate discrimination and renunciation. It was paired with his practice of accepting Dakshina (charitable offerings) to teach that giving up worldly attachments is essential for spiritual progress.
