How did Balaji Nevasakar's mother-in-law demonstrate her faith in Sai Baba during the Shraddha ceremony?

Balaji Nevasakar's mother-in-law demonstrated profound and practical faith during his Shraddha ceremony when faced with a severe food shortage. When the number of guests tripled, causing her daughter-in-law to panic, she remained steadfast. According to Chapter 35, her faith was great, and she immediately invoked Sai Baba's power, asking, 'While he is there, why worry?' Instead of despairing, she took decisive, faith-based action. She took a handful of Udi, a sacred ash, and put it into every pot of prepared food before covering them with cloths. This act was a powerful display of her conviction that Sai Baba's grace could overcome any material challenge, turning a moment of potential humiliation into a testament of faith.
