Can you explain how Radhakrishnabai's use of Udi during the Shraddha ceremony demonstrated the principle of faith?

There appears to be a confusion of characters based on the source text. While Chapter 35 mentions Radhakrishnabai as a devoted individual who performed the service of sweeping Baba's paths, it was not her who used Udi during the Shraddha ceremony. The miracle of the multiplying food is attributed to Balaji Patil Nevasakar's mother-in-law. It was she who, upon realizing the food would be insufficient, exhibited great faith. She put a handful of Udi into the cooking pots and trusted Sai completely. Her faith was rewarded when all the guests were fed, and the pots remained full, illustrating the principle that one's experience aligns with their inner feeling of devotion.
