Based on Chapter 33, what is the significance of the Dhuni, and how does it relate to the concepts of Maya and Brahman?

In Chapter 33, the constantly burning Dhuni (sacred fire) is presented as the source of the Udi, which itself is a profound symbol. The chapter poses the question of why the Dhuni was always kept burning, implying a deeper purpose. The Udi produced from this fire is explained as a sign representing a fundamental truth: 'Brahman alone is real, the cosmos is infinite,' and the entire universe is 'pervaded by Maya (illusion).' By offering logs into the Dhuni to create ash, Baba demonstrated the transformation of the material into its essential, final state. The chapter instructs the reader to accept this meaning with certainty, positioning the Dhuni and its Udi as a constant, practical lesson on distinguishing the real (Brahman) from the illusory (Maya).
