How did the faith of Nevasakar's family play a role during the Shraddha ceremony described in the text?

The family's faith was the pivotal element during the Shraddha ceremony for Balaji Nevasakar. Faced with a severe food shortage due to an unexpectedly large number of guests, the daughter-in-law grew anxious. However, the mother-in-law's faith was unwavering. According to Chapter 35, she confidently stated, "Our Sai is powerful and firm; While he is there, why worry?" This deep-seated belief prompted her to use Sai Baba's Udi in the food pots, demonstrating a complete reliance on his divine intervention to overcome the crisis, rather than succumbing to panic.
