What miracle occurred during Balaji Nevasakar's anniversary feast, and what was the catalyst for it?

During Balaji Nevasakar's Shraddha, or anniversary ceremony, a miracle of abundance occurred. The narrative in Chapter 35 recounts that food was prepared for an estimated number of guests, but the actual number of attendees turned out to be triple the estimate. This caused the woman of the house great anxiety about a potential food shortage and public humiliation. The catalyst for the miracle was the unwavering faith of Balaji's mother-in-law. She calmed her daughter-in-law by expressing her firm belief in Sai Baba's power. She then took a handful of Udi, put it in each pot of food, and covered them, turning a moment of crisis into a demonstration of faith.
