Beyond physical cures, what is the deeper spiritual significance of Sai Baba's Udi as conveyed by Hemadpant?

Hemadpant, in Chapter 33, elevates the significance of Udi beyond a mere remedy for physical ailments. He equates Udi to the 'ornament of Shankara (Shiva),' linking it to the highest divine principle and highlighting its power to remove obstacles for those who discuss its glory with faith. The narrative itself, centered on Udi's miracles, is presented as a 'feast of sweet story-nectar' and a 'feast of self-bliss.' This metaphor suggests that engaging with these stories provides spiritual nourishment and satisfaction that worldly life cannot offer. Therefore, Udi is not just a substance but a symbol and a medium for experiencing Sai's grace, leading to spiritual purification, contentment, and self-bliss.
