Chapter 33 mentions the Dhuni and Udi. How does this chapter connect the physical practice of maintaining the sacred fire with the metaphysical teaching of Brahman and Maya?

Chapter 33 masterfully connects Sai Baba's physical actions with profound metaphysical teachings. The chapter begins by describing the practical aspects: Baba would buy firewood bundles, offer the dry logs into the sacred Dhuni, and distribute the resulting Udi. It then poses the question of the Udi's significance and provides a deep philosophical answer. The text explains that the Udi symbolizes the transient nature of the entire visible universe. This physical ash is a sign that Brahman alone is the ultimate reality, while the cosmos is an infinite illusion, or Maya. Therefore, as detailed in Chapter 33, the daily ritual of the Dhuni and Udi served as a constant, tangible reminder of the non-dualistic truth that all forms, including our own bodies, will eventually return to ash.
