Can you explain the power of Sai Baba's Udi as described in the story of the Nevasakar family's feast?

The story of the Nevasakar family's feast beautifully illustrates the miraculous power of Sai Baba's Udi. During an anniversary ceremony (Shraddha), the family found they had three times more guests than expected, leading to a potential food shortage. As detailed in Chapter 35, the faithful mother-in-law took a handful of Udi, placed it in each cooking pot, and covered them. With immense faith, she declared the food was from Sai. Miraculously, all the guests were fed to their satisfaction, and the food in the pots remained just as full as before, demonstrating how Udi, combined with unwavering faith, can resolve impossible situations.
