What is the deeper spiritual significance of Udi as described in the Satcharita? Is it compared to anything sacred?

In Chapter 33, Udi is presented as much more than a simple healing ash; it is imbued with profound spiritual significance. The text makes a powerful and direct comparison by stating, "Udi is also the ornament of Shankara (Shiva)." This equates Baba's Udi with the sacred vibhuti worn by Lord Shiva, a potent symbol in Hinduism representing purity, detachment, and divinity. This comparison elevates Udi to a sacred substance. The chapter reinforces this by claiming that simply having a discussion about the glory of Udi with genuine feeling and faith is enough to cause the immediate removal of obstacles, highlighting its inherent spiritual power beyond its physical properties.
