How did the Nevasakar family demonstrate their faith, particularly during their father's Shraddha ceremony, and what role did Sai Baba's Udi play?

The Nevasakar family's faith was profoundly tested and proven during Balaji Nevasakar's anniversary ceremony, or Shraddha. As described in Chapter 35, when the family realized they had prepared food for far fewer guests than had arrived, the mother-in-law displayed immense faith. Instead of panicking, she declared her firm belief in Sai's power. She took a handful of Udi, put some in each pot of food, and instructed her daughter-in-law to serve without worry. Because of her resolve and the power of the Udi, the food miraculously multiplied, serving triple the expected number of guests and even leaving leftovers, thus preserving the family's honor.
