What is the scientific explanation for how the Udi multiplied the food during the Nevasakar's feast, and what are its physical properties?

The excerpts from Chapter 35 do not provide a scientific explanation or describe the physical properties of the Udi. The narrative presents the multiplication of food as a miraculous event rooted in faith, not physics or chemistry. When the family faced a food shortage, the mother-in-law, possessing "great faith," placed a handful of Udi into the food pots. The text attributes the subsequent abundance of food to this act of faith and the spiritual "influence of the Udi." It concludes that the experience aligns with the devotee's feeling, stating, "Whatever the feeling in one's mind, so is the experience." Thus, the explanation provided is entirely spiritual in nature.
