What are some of the different ways devotees used Sai Baba's Udi according to the provided excerpts?

The excerpts from Chapter 35 illustrate that devotees used Sai Baba's Udi to resolve various types of crises, believing it would give the desired result. For instance, a gentleman who was suffering from bad dreams and broken sleep found relief by keeping a packet of Udi under his pillow every night. This simple practice, combined with his worship of Baba's picture, completely removed his hardship. In another wonderful instance, Udi was used to avert social humiliation. When the Nevasakar family faced a food shortage during a large feast, Balaji's mother-in-law put a handful of Udi in each food pot, which miraculously multiplied the food to feed everyone.
